Title:

ORGANIC EL PANEL

Document Type and Number:

WIPO Patent Application WO/2011/055621

Kind Code:

A1

Abstract:

Provided is an organic EL panel which is passively driven and is capable of preventing variations in wiring resistance of electrode wirings without restricting the degree of freedom for wiring design and improving evenness in brightness of an organic EL element. The organic EL panel is formed of a light-emitting display unit (2) having a plurality of first electrode lines (2a) formed on a support substrate (1), an organic light-emitting layer (2d) formed on the first electrode lines (2a), and a plurality of second electrode lines (2e) formed so as to intersect the first electrode lines (2a). The organic EL panel has a plurality of electrode wirings (4) which is formed by being routed on the support substrate (1) so as to be connected with the second electrode lines (2e) or the first electrode lines (2a), and the electrode wirings (4) each have parts (4a, 4c) each of which is formed of one wiring and/or a part (4b) in which a plurality of wirings are connected in parallel with each other. The numbers of wirings provided in parallel are set to be different in an area where the wirings are formed in the same direction so that the difference in the wiring resistance between the electrode wirings becomes 5 Ω or less.
