Embodiment

[0069] Such as figure 2 As shown in , the organic EL panel 20 is a COG-type organic EL panel, and includes: a support substrate 21, a light-emitting display portion 22 provided on the support substrate 21, and a sealing member mounted on the support substrate 21 and covering the light-emitting display portion 22. 13. A driver IC 23 provided on the support substrate 21 outside the sealing member 13 , and a plurality of anode wires 12 and a plurality of cathode wires 24 extending from the driver IC 23 to the light-emitting display portion 22 .

[0070] The plurality of anode wires 12 are wires that connect the anode electrodes to the driver IC 23, and are made of a low-resistance conductive material such as ITO and / or chromium (Cr), aluminum (Al), or their alloys, which are the same material as the anode electrodes. Or their laminated body is formed.

[0071] The plurality of anode wires 12 are divided into a center group 25C as a first group that is a first group that is dire...

Abstract

The problem addressed by the present invention is to provide an organic EL panel with a structure that suppresses occurrences of wire breakage even if adhesive parts protrude. Just a small amount of adhesive protrudes from the bottom surface of a sealing member 13 constituting the organic EL panel. The protruding length of a protruding adhesive part 11 is approximately 0.3 mm. Wire breakage trouble occurs if the length La of a portion where positive electrode wiring 12 overlaps the protruding adhesive part 11 is large as is shown in FIG. (a), and wire breakage trouble ceases to occur if a length Lb for the portion where the positive electrode wiring 12 overlaps the protruding adhesive part 11 is made short as is shown in FIG. (b). Furthermore, if the length Lc of the portion where the positive electrode wiring 12 overlaps the protruding adhesive part 11 is made even shorter as is shown in FIG. (c), wire breakage trouble reliably ceases to occur. The organic EL panel can be made larger because wire breakage trouble can be avoided.

Description

technical field [0001] The present invention relates to an organic EL panel, and particularly to improvement of the wiring structure of the organic EL panel. Background technique [0002] Light is emitted when a voltage is applied to certain organic compounds. A panel using such a light-emitting organic substance as a light source is called an organic EL (Electro Luminescence: electroluminescence) panel. [0003] The structure of various organic EL panels has been proposed (for example, refer to Patent Document 1 ( figure 1 , Figure 4 )). [0004] The patent document 1 Figure 4 as well as figure 1 shown again in Figure 8 as well as Figure 9 . Symbols have been renumbered. [0005] Such as Figure 8 (equivalent to the Figure 9 As shown in the cross-sectional view along the line 8-8 of ), the organic EL panel 100 has the following components as its main elements: a support substrate 101 , which is disposed on the support substrate 101 and sandwiched by a pair o...
