More specifically, the present invention relates to an electro-optical device with improved electrical connection between upper and lower electrodes. [Prior Art] Conventionally, when driving a liquid crystal by applying a voltage to the upper and lower transparent electrodes of an electro-optical device, one transparent electrode is electrically connected to the other transparent electrode through the upper and lower conductive parts. As a method for facilitating the connection between the electro-optical device and the circuit section by consolidating the drive terminals of the liquid crystal on the other side of the substrate (Japanese Unexamined Patent Publication Nos. 53-43306 and 59-86026). A device with conductive particles installed in the seal part as shown in JP-A-59
28186 or Japanese Patent Laid-Open No. 59-28185, a method has been proposed in which conductive particles are installed in the seal portion with a diameter that is approximately the same as the thickness of the liquid crystal layer. Also, (Unexamined Japanese Patent Publication No. 5
8-182685 (Japanese Patent Laid-Open No. 58-33220), a method is known in which conductive particles are made to have elasticity and are set to be slightly thicker than the diameter of the gap material to ensure a gap in the liquid crystal layer. ing. 1. Problems to be Solved by the Invention] However, in the above-mentioned prior art
306, JP-A-59-28186, JP-A-59-281
No. 85, JP-A No. 59-86026), the diameter is the same as the thickness of the liquid crystal layer, or the conductive particles themselves also serve as a spacer material, so the electrical contact becomes point contact and the resistance value becomes high. Since continuity could not be ensured, there was a problem that 18 reliability was lowered.Therefore, as a Q improvement for the above problem (JP-A-58-18265, JP-A-58-3322)
In No. 0), the seal part and the adhesive part in which elastic conductive particles are dispersed are installed in separate locations, or the elastic conductive particles are installed in the seal part to also serve as a spacer material. The uniformity of the thickness of the seal part is determined by the elastic conductive particles, so when pressure is applied to the seal part during manufacturing, the deformation rate of the elastic conductive particles changes due to pressure variations, resulting in non-uniformity of the liquid crystal layer. This has the problem that it tends to cause deterioration in appearance and appearance quality. SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and its purpose is to easily provide an electro-optical device having a uniform liquid crystal layer thickness, high reliability, and a lower conductive portion. It's about doing. [Means for Solving the Problems] A first electro-optical device of the present invention is composed of a pair of substrates having transparent electrodes on their inner surfaces, and a conductor connecting the electrodes of one substrate to the electrodes of the other substrate. The electro-optical device has a spacer disposed in the sealing part, and the electro-optical device is characterized in that the diameter of the conductive particles is larger than the diameter of the spacer disposed in the sealing part. A second electro-optical device of the present invention is characterized in that the conduction particles are an elastic body, and the spacer has a smaller deformation rate than the conduction particles. A third electro-optical device of the present invention is characterized in that the spacer is formed of galley fiber. A fourth electro-optical device of the present invention is characterized in that the conductive portion is provided in a portion of the seal portion corresponding to the alternating transparent electrode portions of the upper and lower substrates. [Function] According to the above structure of the present invention, the storage of the liquid crystal layer q is determined by the spacer material dispersed in the sealing part, and the upper and lower conduction is made using a material having a diameter larger than that of the spacer material and a modulus of elasticity. The large conductive particles change and come into strong and planar contact with the conductive portion, thereby eliminating contact failure. In addition, because the conductive particles are sufficiently deformed, even if the conductive particles have slightly different diameters or unevenness on the upper and lower substrates, they all come into strong surface contact, so the conductivity does not depend on one place. The effect of uniformity also occurs. (Example) Hereinafter, the present invention will be explained in detail using Examples. Fig. 1 shows an electro-optical device shown in a first example of the present invention. l is approximately the same as the thickness of the liquid crystal layer. Glass beads 5 are non-conductive spacer materials such as rough fibers.2 are polystyrene polymers, vinyl chloride-hinyl acetate co-mers, chloroprene-based (co) 1-combiners, and butadiene-based polymers such as butadiene-styrene. Gold, silver, tin, copper, nickel, etc. are conductive particles made of a plastic ball or plastic fiber made of an elastic high-molecular compound such as a polymer or polyurethane, and the surface is coated with an oil-based coating. The conductive material 1 is formed on the plastic ball or plastic fiber by electroless plating. In this case, different types of conductive materials may be formed in multiple layers. 3 is an adhesive for forming the sealing part, which may be epoxy, Synthesis of phenol, vinyl acetate, urea vinyl chloride, resorcinol, acrylic, etc. 1
Degreasing is used. In the above-mentioned structure of the seal part, the amount of spacer material in the seal part is suitably 0.1 to 30 wt% based on the contact strength and the uniformity of the liquid crystal layer, and the density of the conductive particles is such that a large number of them are present in one conductive part. A better electrical connection can be obtained by setting the
[Example 11 Transparent electrodes 6 and 7 were formed on the glass substrates 4 and 5, respectively, using indium oxide-oxide. The transparent electrode 6.7 was formed using tin (hereinafter referred to as 1To).
Polystyrene electrolessly plated with nickel having the diameter and number shown in Table 1 was dispersed as conductive particles 2 in a thermosetting epoxy resin and formed by a screen printing method. After that, thermosetting epoxy I elbow grease was used as the sealing part 3, and the spacer material L was made of glass fiber 7Uφ, and the conductive particles 2
The other parts were formed as shown in FIG. Then 0,
150 at a pressure of 40 K g f/cm”
Heat of C was applied to harden the thermosetting epoxy resin. At this time, as shown in FIG. 2, an electro-optical device was formed using the alignment layer 8 and the gap material 7, Ou glass fiber, and liquid crystal 10, and the oil conductivity was confirmed by the (:i !l property test). The results are also shown in Table 11. Table 1. Conductive particle diameter and defect rate The above results show that reliability is significantly improved by making the diameter of the conductive particles larger than the diameter of the spacer material. However, if it is 13 times or more larger than the spacer diameter,
There is concern that cracks will occur in the conductive material on the surface of the 27i particles, resulting in a decrease in conductivity. Therefore, the diameter of the conductive particles is
Even slightly larger than the diameter of the spacer material, the limit is 1.3
Double the amount is considered appropriate. In addition, all the appearances were uniform. [Example 2] Instead of the thermosetting epoxy resin shown in Example 1, conductive particles were mixed with ultraviolet curable epoxy acrylate resin and screen printing was performed.Then, the sealing part was also made of glass fibers in the epoxy acrylate resin. Same as above (after forming by screen printing, 0.45Kgf/C
250-30 at a wavelength of 250-400 nm at a pressure of m'
When a seal portion was formed by irradiating the seal portion with an intensity of 0 mJ/cm, the same results as in Example 1 were obtained.In this example, the method for forming the seal portion was explained using a screen printing method. However, the same result can be obtained by any method such as brush painting, offset printing, etc. [Advantage of the invention 1] As described above, according to the present invention, the thickness of the liquid crystal layer in the seal portion is formed by the spacer material. By forming a conductive part using elastic conductive particles with a larger diameter than the spacer, the conductivity of the electro-optical device is significantly improved, and the uniformity of the liquid crystal layer and the strength of the seal part are also improved, which improves the display quality. This produces the effect that a uniform electro-optical device can be provided.
