Patent ID: 8242503

Claim:
A system for displaying images, comprising: a multi-gate thin film transistor device comprising: a substrate having a pixel region; an active layer disposed on the substrate in the pixel region, comprising a first source/drain region, a second source/drain region, a first channel region, a second channel region, and a channel connection region, wherein the first channel region adjoins a first lightly doped region of the first source/drain region with a third lightly doped region of the channel connection region, and the second channel region adjoins a second lightly doped region of the second source/drain region with a fourth lightly doped region of the channel connection region; a first gate structure and a second gate structure disposed on the active layer and corresponding to the first and second channel regions, respectively, wherein the first and second gate structures are electrically connected to each other; and a first light-shielding layer and a second light-shielding layer disposed between the substrate and the active layer, wherein the first light-shielding layer corresponds to the first lightly doped region and laterally extends under at least a portion of the first channel region, and the second light-shielding layer corresponds to the second lightly doped region and laterally extends under at least a portion of the second channel region.
