Abstract:
1. A method for forming a panel comprising a thin film transistor, the method comprising: forming a light blocking layer on a substrate; forming a first protective film on the light blocking layer; forming a first electrode and a second electrode on the first protective film and spaced apart from each other; forming 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 first electrode and the second electrode; forming an insulating layer on the oxide semiconductor layer, the first electrode, and the second electrode; forming a third electrode overlapping the oxide semiconductor layer and on the insulating layer; and forming a fourth electrode on the insulating layer and connected to the second electrode, wherein the light blocking layer, the first protective film, the first electrode, and the second electrode are formed using a single mask.
