The wire 13 includes a bottom bonding layer which is coated on the substrate and spaced apart from the light emitting unit 112. 131, and a top bonding layer 132 stacked on the bottom bonding layer I. The cathode 113 is extended and overlapped on the top bonding layer 132, the substrate 1 and the light emitting unit 112. The bottom bonding layer 131 is a conductive film material which is preferably combined with the substrate 1 , such as Indium Tin Oxide (Indium Tin Oxide), which has a chemical formula of InSn〇3 and has a phase interval adjacent thereto. The end portion 13 of the light-emitting unit ι 2 is distinguished from the end portion 13 by an imaginary line in the drawing. The top bonding layer 132 is formed of a metal film such as chrome, and is overlapped at the end portion 134 by an end portion 135 thereof. In the above, the end portion 135 is also distinguished by an imaginary line. The cathode 113 is also made of a gold-based film such as aluminum, and its end portion ι 4 φ corresponds to the area and position of the end portion 134 bonded to the top joint. In the layer 132, the end portion 1 14 is also distinguished by an imaginary line. Since the anode 111 and the cathode 113 are the two electrode ends when the power source is supplied, the contact resistance value of the cathode 113 and the wire π is It has an important influence on the luminance of the overall organic electroluminescence diode 11. The bottom junction & 131, the top bonding layer 132 and the cathode 113 are combined to form a k, and the contact resistance of the integral conductor 13 and the cathode 113 is 173.2. 6 1247251 Ω. Again, the response system The wire 13 sometimes further includes an electron injecting layer bonded between the top bonding layer 132 and the cathode ι13, and the electron injecting layer is not shown in the figure. The bottom bonding layer 131, the top bonding layer 132, and the electron injecting layer The layer is combined with the cathode 113, and the contact resistance value generated by the integral wire 13 and the cathode 113 is 331 Q. The magnitude of the contact resistance between the wire 13 and the cathode 113 is directly when the organic electroluminescence diode 11 is energized. Affecting the intensity of its brightness, the greater the contact resistance value of the wire 13 and the cathode 113, the weaker the brightness of the organic:excitation light diode 11. Conversely, the smaller the impedance value of the wire 13 and the cathode m, the stronger the luminance of the organic electroluminescence photodiode n.

The 4 wire 4 includes a bottom layer bonded to the substrate 3 in sequence. a layer 41, and a top bonding layer 42. The bottom bonding layer 41 is coated on the substrate 3 and has an end portion 4丨丨 adjacent to the package/lighting light body 2, which is an imaginary line in the figure. To distinguish the end neighbor 411. The far bottom bonding layer 41 may be inSn〇3, Sn〇2, doped Zn〇In2〇3, CdSnO, Sb···, etc., as shown in Figures 3 and 4, the top The bonding layer 42 may be formed of an &, Ag ^ , an Ag alloy, an Ag_Au alloy, or the like, and is overlapped at one end portion 42 of the end portion 411 of the bonding layer 41. The imaginary line distinguishes the P 420 so that the edge of the end portion 411 is covered by the end portion, and a hollow hole 421 having a rectangular hole shape is formed in the middle of the end 4 420, so that the end portion 420 is rudder J The end portion 411 of the bonding layer 41 is bonded to the end portion, and the end portion 420 is not completely covered with the end portion 411. The organic electroluminescent diode 2 includes sequentially layered layers. Laminated on the substrate 3 8 1247251 21, the light-emitting unit 22' and the cathode 23.

The cathode crucible can be A! full-drilled:,:::stone, an alloy, a gold, Wchuan The end portion 231 is joined to the top joint layer 42 at an end portion corresponding to the bottom joint layer 41. The figure also assumes the region "the end portion 231' and fills the top joint layer. The 镂4 of 42 is similar to the bottom bonding layer 41*. That is, the end portion 231 of the cathode a is joined to ## τι yv a , and the relative positions on the bottom and top bonding layers 41 and 42 are bonded to the bottom by the upper end portion 411 of the bottom bonding layer 41. On top bonding layers 41, 42. It is worth mentioning that when the end portion of the cathode.μ is filled in the hollow region 421, it also contacts the end portion 420 of the top bonding layer 42 via the periphery of the hollow region 421. The contact resistance value of the measured integrated cathode 23 and the wire 4 is 6.3 Ω by the bottom bonding layer 41, the top bonding layer 42, and the cathode 23 combined structure.

As shown in FIGS. 5 and 6, the second embodiment of the organic electroluminescent display device of the present invention is different from the previous embodiment in that the end 4 420 of the top bonding layer 42 is only connected to the bottom bonding layer. The intermediate portion of 41 is such that a U-shaped edge block 412 of the end portion 411 of the bottom bonding layer is not subjected to the end portion 420 of the top bonding layer. This is substantially the same as the bottom bonding layer of the foregoing embodiment. 41 is enlarged in area, and the area of the top bonding layer 42 is maintained. * As shown in Fig. 7, when the cathode 23 is overlapped on the top bonding layer, the same length is also corresponding to the end of the bottom bonding layer 41.

Of course, the shape of the hollowed out region 421 can be designed into other shapes, such as a circular hole shape. As shown in FIG. 9, when the end portion 231 of the cathode 23 is overlapped on the top bonding layer 42, the area of the top bonding layer 42 corresponding to the bottom bonding layer 41 is also bonded to the top bonding layer 42, so that it is filled in.
