Patent ID: 8598583

Claim:
A panel comprising a thin film transistor, the panel comprising: a substrate; a light blocking layer on the substrate, the light blocking layer comprising first sidewalls; a first protective film on the light blocking layer, the first protective film comprising second sidewalls connecting top and bottom surfaces of the first protective film; a first electrode and a second electrode on the first protective film, the first electrode comprising third sidewalls and the second electrode comprising fourth sidewalls spaced apart from the first electrode; an oxide semiconductor layer on a portion of the first protective film exposed between the first electrode and the second electrode, and on at least a portion of the third sidewalls, the fourth sidewalls, the first electrode, and the second electrode; an insulating layer on the oxide semiconductor layer, the first electrode, the second electrode, the first sidewalls, the second sidewalls, the third sidewalls, and the fourth sidewalls; a third electrode overlapping with the oxide semiconductor layer and on the insulating layer; and a fourth electrode on the insulating layer, the fourth electrode connected to the second electrode, wherein at least a portion of the first sidewalls and at least a portion of the second sidewalls are disposed along substantially the same line.
