Patent ID: 8445910

Claim:
An organic light emitting display, comprising; a substrate; conductive layer formed on the substrate; a first insulating layer formed on the substrate and on the conductive layer; a first electrode layer and an activation layer formed OR the first insulating layer as a semiconductor; a second insulating layer formed on the first insulating layer, the first electrode layer and the activation layer; a gate electrode formed on the second insulating, layer which is formed on the activation layer; a third insulating layer formed on the second insulating layer and on the gate electrode; a second electrode layer formed on the third insulating layer, and coupled to a source region of the activation layer and to the conductive layer; and a third electrode layer formed on the third insulating layer, and coupled to a drain region of the activation layer; wherein the first electrode layer is used as one electrode of a capacitor, and wherein the conductive layer facing the first electrode layer is used as another electrode of the capacitor.
