Abstract:
1. An organic light emitting diode display, comprising: a substrate main body; a semiconductor layer on the substrate main body, the semiconductor layer including an impurity-doped polycrystalline silicon layer; a first capacitor electrode on the substrate main body, the first capacitor electrode including an impurity-doped polycrystalline silicon layer, and bottom surfaces of the first capacitor electrode and semiconductor layer facing the substrate main body being substantially coplanar; a gate insulating layer on the semiconductor layer and the first capacitor electrode; a gate electrode on the semiconductor layer with the gate insulating layer therebetween; a second capacitor electrode on the first capacitor electrode with the gate insulating layer therebetween, bottom surfaces of the second capacitor electrode and gate electrode facing the substrate main body being substantially coplanar, and the second capacitor electrode having a smaller thickness than the gate electrode; and an organic light emitting diode on the substrate main body, a pixel electrode of the organic light emitting diode not overlapping any portion of the second capacitor electrode.
