Abstract:
1. An organic light-emitting display device, comprising: an active layer of a thin film transistor formed on a substrate; a gate electrode of the thin film transistor, wherein a first gate electrode comprising a transparent conductive material, a first insulating layer, and a second gate electrode comprising a metal are sequentially stacked; a pixel electrode disposed on the first insulating layer and the pixel electrode comprising the transparent conductive material; a source electrode and a drain electrode of the thin film transistor, which are electrically connected to the active layer, and a second insulating layer disposed between the source electrode and the drain electrode; a light reflector comprising a same material as the source electrode and the drain electrode, the light reflector being disposed at an upper edge of the pixel electrode; an emission layer emitting light, the emission layer being disposed on top of the pixel electrode and the emission layer being surrounded by the light reflector; and a counter electrode facing towards the pixel electrode, wherein the emission layer is disposed between the pixel electrode and the counter electrode.
