Patent ID: 8415659

Claim:
An organic light emitting diode (OLED) display device, comprising: a substrate including an emission region and a non-emission region; a buffer layer arranged on the substrate; a semiconductor layer arranged in the non-emission region on the buffer layer; a gate insulating layer arranged on an entire surface of the substrate; a first electrode arranged in the emission region and directly on the gate insulating layer; a gate electrode arranged in the non-emission region on the gate insulating layer; an interlayer insulating layer arranged on the entire surface of the substrate and partially exposing the first electrode; source and drain electrodes arranged on the interlayer insulating layer and electrically connected to the semiconductor layer and the first electrode; a protection layer arranged on the entire surface of the substrate and partially exposing the first electrode; an organic layer arranged on the first electrode; and a second electrode arranged on the entire surface of the substrate.
