Abstract
An organic light-emitting display device includes a thin film transistor (TFT) including an active layer, a gate electrode comprising a first electrode and a second electrode, a source electrode, and a drain electrode, a photoresist layer on the source electrode and the drain electrode, a pixel electrode electrically coupled to the TFT, comprising a same material as the first electrode, and at a same layer as the first electrode, a pixel defining layer having a hole exposing the pixel electrode, the pixel defining layer covering the photoresist layer, an intermediate layer on the pixel electrode and comprising a light-emitting layer, and an opposite electrode covering the intermediate layer and facing the pixel electrode.
