There is such an issue with a TFT using an oxide semiconductor film that oxygen deficit is generated in a surface region of the oxide semiconductor film after performing plasma etching of a source-drain electrode, and the off-current becomes increased. Disclosed is the TFT which includes: a gate electrode on an insulating substrate as a substrate; a gate insulating film on the gate electrode; an oxide semiconductor film on the gate insulating film; and a source/drain electrode on the oxide semiconductor film. It is the characteristic of the TFT that a surface layer containing at least either fluorine or chlorine exists in a part of the oxide semiconductor film where the source/drain electrode is not superimposed.
A display device includes pixels having different arrangements of subpixels and reducing a color edge. The display device includes a display unit where a plurality of first pixels including subpixels of three colors and second pixels including subpixels of the three colors are alternately arrayed in row and column directions, an arrangement of the subpixels in the first pixel and an arrangement of the subpixels in the second pixel differing from each other, and a luminance allocation unit allocating luminance of a subpixel of a first color among the three colors in the first pixel to a subpixel of the first color in the second pixel adjacent to the first pixel with a predetermined ratio and allocating luminance of the subpixel of the first color in the second pixel to the subpixel of the first color in the first pixel adjacent to the second pixel with a predetermined ratio.
