Organic EL display and method of manufacturing the same
View Patent ↗An organic EL display including a plurality of pixels each having, in order from a substrate side, a first electrode, an organic layer including a light emission layer, and a second electrode; an auxiliary wiring disposed in a periphery region of each of the plurality of pixels and conducted to the second electrode; and another auxiliary wiring disposed apart from the auxiliary wiring at least in a part of outer periphery of a formation region of the auxiliary wiring in a substrate surface.
1. A method of manufacturing an organic EL display, comprising the steps of:
forming a first electrode for each of pixels on a substrate;
forming an auxiliary wiring in a peripheral region of each of the pixels on the substrate;
forming another auxiliary wiring so as to be electrically insulated from the auxiliary wiring;
forming an organic layer including a light emission layer over the first electrode and the auxiliary wiring;
forming a connection hole in a region corresponding to the auxiliary wiring in the organic layer by applying a reverse bias voltage to the organic layer via the auxiliary wiring and the another auxiliary wiring; and
forming a second electrode so as to bury the connection hole on the organic layer.
2. The method of manufacturing an organic EL display according to claim 1 , further comprising the steps of:
forming the organic layer and the another auxiliary wiring; and
forming, on the organic layer, a third electrode so as to be electrically insulated from the auxiliary wiring and to be conductive with the another auxiliary wiring, and applying a reverse bias voltage to the organic layer.
