Abstract
An organic light-emitting display device includes: a substrate; a pixel electrode on the substrate; an auxiliary electrode spaced apart from the pixel electrode; a first insulating film between the pixel electrode and the auxiliary electrode and covering an end of the pixel electrode and an end of the auxiliary electrode; an intermediate layer on the pixel electrode and including an emission layer; an opposite electrode covering the intermediate layer and contacting the auxiliary electrode; and a passivation layer covering the opposite electrode.
Claims5
A method of manufacturing an organic light-emitting display device, the method comprising:
- simultaneously forming a pixel electrode and an auxiliary electrode on a substrate;
- forming a first insulating film between the pixel electrode and the auxiliary electrode to cover an end of the pixel electrode and an end of the auxiliary electrode;
- sequentially forming a lift-off layer and a photoresist on the pixel electrode, the auxiliary electrode, and the first insulating film;
- forming an opening exposing an upper surface of the pixel electrode by patterning the lift-off layer and the photoresist;
- sequentially forming an intermediate layer comprising an emission layer, an opposite electrode, and a passivation layer in the opening and on the photoresist, wherein the opposite electrode in the opening contacts the auxiliary electrode while covering the intermediate layer;
- and
- removing the lift-off layer and the photoresist.
