Patent ID: 8618545

Claim:
A thin film transistor comprising: a gate electrode; an active layer; a source electrode and a drain electrode on the active layer; a gate insulating film arranged between the gate electrode and the active layer, the gate insulating film including a first insulating film, a first light-absorbing layer and a second insulating film, the first insulating film being arranged in contact with the gate electrode, the first light-absorbing layer being arranged in contact with the first insulating film, and the second insulating film being arranged between the first light-absorbing layer and the active layer; an interlayer insulating film covering the gate electrode, the gate insulating film, the active layer, and the source and drain electrodes, the interlayer insulating film being arranged in contact with the source and drain electrodes; and a second light-absorbing layer arranged in contact with the interlayer insulating film, wherein, the second light-absorbing material (i) is made of the same material as a material of which the first light-absorbing layer is made and (ii) has the same thickness as a thickness of the first light-absorbing layer.
