Patent ID: 8124975

Claim:
A display device, comprising: a semiconductor film comprising a plurality of channel regions formed in series between an image signal line and a pixel electrode with impurity doped regions in which predetermined impurities are doped being interposed between any two adjacent channel regions among the plurality of channel regions, the plurality of channel regions comprising at least a first channel region and a second channel region; a light source which generates light, the light source being disposed on one side of the semiconductor film; and a gate electrode film formed between the semiconductor film and the light source, the gate electrode film comprising: a first gate region spreading over a region opposed to the first channel region of the semiconductor film on a side of the light source; and a second gate region spreading over a region opposed to the second channel region of the semiconductor film on the side of the light source, wherein a relative area of the first gate region with respect to the first channel region is different from a relative area of the second gate region with respect to the second channel region.
