Patent ID: 8513671

Claim:
A display device comprising: a substrate that comprises a first area, a second area, and a third area; semiconductor layers that are formed on the first area and the second area of the substrate and that comprise in each area a channel area and source/drain areas; gate insulating layers that are formed on the semiconductor layers and that are formed in the areas corresponding to the channel areas; a gate electrode that is formed on each gate insulating layer; source/drain electrodes that directly contact the source/drain areas, respectively, of the semiconductor layers; a pixel electrode that is formed in the same layer as that of the source/drain electrodes and that is formed in the third area; an interlayer insulating layer that is formed on the whole surface of the substrate including the source/drain electrodes and the pixel electrode; and a gate line that is formed on the interlayer insulating layer and that is electrically connected to the gate electrode of the first area through a via contact hole of the interlayer insulating layer.
