Patent ID: 7888679

Claim:
A display device comprising: a substrate; a light blocking member disposed on the substrate, wherein the light blocking member contains nickel and silicon oxide; a semiconductor layer disposed on the light blocking member and comprising a channel region; a gate insulating layer disposed on the semiconductor layer; gate conductors disposed on the gate insulating layer; a first interlayer insulating layer disposed on the gate insulating layer and the gate conductors; data conductors disposed on the first interlayer insulating layer; a second interlayer insulating layer disposed on the data conductors and the first interlayer insulating layer; a pixel electrode disposed on the second interlayer insulating layer; a third interlayer insulating layer having an opening extending to the pixel electrode; an organic light emitting member formed inside the opening; and a common electrode disposed on the organic light emitting member and the third interlayer insulating layer; wherein the channel region of the semiconductor layer overlaps with the light blocking member.
