Abstract:
1. A display device comprising a thin film transistor, the thin film transistor comprising: a gate insulating film having a major surface; a semiconductor layer on a portion of the major surface, the semiconductor layer comprising a gate electrode, the gate insulating film being disposed between the semiconductor layer and the gate electrode; a first channel protection film covering the third portion of the semiconductor layer; a second channel protection film covering the fifth portion, the fourth portion, and an upper surface of the first channel protection film; a first conductive layer covering the sixth portion, a portion of the second channel protection film being disposed between the first conductive layer and the fourth portion; a second conductive layer covering the seventh portion, a portion of the second channel protection film being disposed between the second conductive layer and the fifth portion; and a passivation film covering the first portion, the second portion, the first conductive layer, the second conductive layer, and the second channel protection film, the passivation film physically contacting the first portion and the second portion, and the passivation film including not less than 1.0×10 wherein the fourth portion includes a portion on a side of the second channel protection film, and a resistivity of the portion of the fourth portion on the side of the channel protection film is not less than 1.0×10
