Abstract:
The purpose of the invention is to form the TFT of the oxide semiconductor, in which influence of variation in mask alignment is suppressed, thus, manufacturing a display device having a TFT of stable characteristics. The concrete measure is as follows. A display device including plural pixels, each of the plural pixels having a thin film transistor (TFT) of an oxide semiconductor comprising: a width of the oxide semiconductor in the channel width direction is wider than a width of the gate electrode in the channel width direction.
