Patent ID: 8421337

Claim:
An organic light emitting diode (OLED) display device comprising: a substrate; a thin film transistor on the substrate and including a semiconductor layer, a gate electrode, a gate insulating layer, a source electrode contacting the semiconductor layer through the gate insulating layer, and a drain electrode contacting a drain region of the semiconductor layer through the gate insulating layer; a passivation layer on substantially an entire surface of the substrate including the thin film transistor; a planarization layer on the passivation layer; a first electrode on the planarization layer and electrically coupled to at least one of the source electrode or the drain electrode; a metal mixture layer on substantially the entire surface of the substrate and including a conductive region having an upper surface and a non-conductive region having an upper surface that is level with the upper surface of the conductive region, the conductive region being located on the first electrode and not being in contact with the planarization layer, and the non-conductive region contacting the planarization layer; and an organic emitting layer and a second electrode both on the metal mixture layer.
