Abstract: Provided is a method of manufacturing a light-emitting display device. The method of manufacturing a light-emitting display device may comprise: forming a first electrode on a substrate, the substrate having a plurality of first pixel areas and a plurality of second pixel areas, the first electrode being formed in each of the first and second pixel areas such that corresponding first and second pixels are formed; forming a pixel defining layer on the substrate, the pixel defining layer having an opening exposing the first electrode of each of the first and second pixels; forming a first photoresist pattern on the pixel defining layer, the first photoresist pattern having a first pattern opening exposing the first electrode of each of the first pixels; forming a light-emitting layer on the first electrode exposed through the first pattern opening; and removing the first photoresist pattern.

Abstract: In an aspect, an organic light emitting diode display including: a substrate; a first electrode and an auxiliary electrode positioned on the substrate and separated from each other; an absorption electrode positioned on the auxiliary electrode; an organic emission layer positioned on the first electrode and having a contact hole exposing the auxiliary electrode and the absorption electrode; and a second electrode positioned on the organic emission layer and connected to the auxiliary electrode and the absorption electrode through the contact hole is provided. In an aspect, the organic light emitting diode (OLED) display may minimize the voltage drop of the driving power passing through the large-sized electrode of the thin film for driving the organic emission layer, and may simplify the removal process of the organic emission layer on the auxiliary electrode by adding the absorption electrode on the auxiliary electrode.
