Organic light-emitting display device

摘要

An organic light-emitting display device includes a substrate; a gate electrode disposed on the substrate, the gate electrode including a first portion of a metal oxide layer and a metal layer; a pixel electrode disposed on the substrate and including a second portion of the metal oxide layer; a gate insulating layer covering the gate electrode; a semiconductor layer disposed on the gate insulating layer and including a channel region, and first and second regions disposed outside the channel region; a first electrode connected to the first region; a second electrode connected to the second region and the pixel electrode; an ohmic contact layer disposed between the first region and the first electrode and between the second region and the second electrode; a pixel defining layer including an opening exposing the pixel electrode; an organic light-emitting layer disposed on the pixel electrode; and an opposite electrode covering the organic light-emitting layer.
