ORGANIC LIGHT-EMITTING DISPLAY APPARATUS AND METHOD OF MANUFACTUING THE SAME

摘要

Provided is an organic light-emitting display apparatus including a thin-film transistor (TFT) that includes an active layer, a gate electrode, and source/drain electrodes; an organic light-emitting device that includes a pixel electrode which is connected to the TFT, an intermediate layer which includes a light-emitting layer, and an opposite electrode; and an opposite electrode contact unit in which the opposite electrode is electrically connected to a power wiring, wherein, with regard to the power wiring, a surface that contacts the opposite electrode is formed to have an embossed structure.

主权项

1. A method of manufacturing an organic light-emitting display apparatus, the method comprising:
forming a first conductive layer and a second conductive layer on a substrate; patterning the first conductive layer and the second conductive layer to form a pixel electrode and a first wiring layer of a power wiring from the first conductive layer, and to form a second wiring layer of the power wiring from the second conductive layer; forming an interlayer insulating layer that comprises a hole exposing a part of the pixel electrode and the second wiring layer; forming a third conductive layer on the interlayer insulating layer, and patterning the third conductive layer to form a third wiring layer of the power wiring that has an embossed structure on an upper surface of the power wiring; forming a pixel-defining layer exposing a part of the pixel electrode and the third wiring layer of the power wiring; and forming an opposite electrode on the pixel-defining layer in the form of a front electrode, which is electrically connected to the third wiring layer of the power wiring.
