Patent ID: 8324629

Claim:
An organic light emitting display device, comprising: a transparent substrate having a first region and a second region; an anode electrode in the first region, wherein the anode electrode comprises a transparent material; a gate electrode in the second region, wherein the gate electrode comprises the transparent material and an oxide semiconductor material; an insulating layer formed on the anode electrode and the gate electrode, wherein the insulating layer is patterned to expose the anode electrode in a light emitting region; an active layer formed on a portion of the insulating layer over the gate electrode, wherein the active layer comprises the oxide semiconductor material and includes a channel region, a source region, and a drain region; a first passivation film formed on the insulating layer and the active layer, wherein the first passivation film is patterned to expose the active layer in the source and drain regions and to expose the anode electrode in the light emitting region, wherein the first passivation film remains on the channel region of the active layer; a source electrode connected to the exposed anode electrode and to the exposed active layer in the source region; a drain electrode connected to the exposed active layer in the drain region; an organic light emitting layer that is formed on the exposed anode electrode; and a cathode electrode that is formed on the organic light emitting layer.
