Description of the Related Art In a liquid crystal panel, as shown in FIG. 2, a matrix electrode substrate 1 and a color filter substrate 2 are opposed to each other, and spherical spacers 3 and 6 are interposed between the two substrates so as to maintain a constant gap therebetween. Then, the liquid crystal 4 is injected and sealed with the sealing material 5. Therefore, the spherical spacer 6 for maintaining the space between the two substrates at the portion where the sealing material is applied.
Has a larger diameter than the spherical spacer 3 interposed at the position where the colored layer 7 of the color filter exists.

た。In this conventional structure for controlling the distance between both substrates of a liquid crystal panel, two kinds of spacers having different diameters are used in one type of panel. Furthermore, if the color layer thickness differs due to differences in product type and color filter supplier, etc., a different combination of spacers must be used for each color filter substrate. Since two types of spacers are used in this way, the combination of spacer diameters is 0.1 μm.
However, if they are misaligned, the panel gaps will be slightly different, which causes a problem of different colors in display. In addition, since two types of spacers are used as a reference for each product type and each color filter supplier, there is a problem in that member management becomes complicated.

止できる。The present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a panel according to an embodiment of the present invention. In this embodiment, the color filter substrate 2 has a colored layer 7 formed in addition to the display portion other than the transfer pad portion to make the surface shape of the substrate uniform. Next, in order to improve the adhesion between the sealing material 5 and the color filter substrate 2, an adhesion enhancer such as silane is applied. Next, the spacer mixed in the sealing material 5 is the same spherical spacer 3 as the display portion. When the liquid crystal panel is assembled by using the sealing material with the color filter substrate 2 and the matrix electrode substrate 1 facing each other, the distance between the surface of the color filter substrate 2 and the matrix electrode substrate 1 becomes uniform, and the cell gap thickness of the liquid crystal panel is controlled. Becomes easier,
It is possible to prevent display unevenness due to the difference in cell gap thickness.

微妙な色味の違いを解消できる。In the present invention, even if the color filter substrate 2 having the same spectral characteristic has a different thickness of the colored layer 7, the present invention has a structure in which the distance between the surface of the color filter substrate 2 and the matrix electrode substrate 1 is kept uniform. When driving a liquid crystal panel using color filters having different colored layer thicknesses, it is possible to eliminate subtle color differences.

This has the effect of reducing display unevenness caused by fluctuations in the distance between both substrates.
Although the spectral characteristics are the same, even if color filter substrates with different film thicknesses are used, it is possible to maintain a uniform gap between both substrates, and there is a slight difference in color when driving. There is an effect that can be solved.
