Patent ID: 8592832

Claim:
An organic light emission diode (OLED) display device, comprising: a substrate comprising a pixel region and a non-pixel region; a buffer layer disposed on the substrate; a semiconductor layer disposed on the buffer layer, and comprising a channel region, and source and drain regions; a gate electrode disposed to correspond to the channel region of the semiconductor layer; a gate insulating layer disposed between the semiconductor layer and the gate electrode; source and drain electrodes electrically connected to the source and drain regions, respectively, of the semiconductor layer; an interlayer insulating layer disposed between the gate electrode and the source and drain electrodes; and a first electrode, an organic layer, and a second electrode that arc electrically connected to one of the source and drain electrodes, wherein an area of the buffer layer, the gate insulating layer, and the interlayer insulating layer is partially removed from the non-pixel region, and the area that is partially removed corresponds to 8% to 40% of a total area of the substrate.
