Abstract:
1. A display device comprising: a first signal line provided so as to be supplied with a first image signal in a first horizontal scan period which is included in a first sampling period, and supplied with a second image signal in a second horizontal scan period which is included in a second sampling period; a second signal line provided so as to be supplied with a third image signal in the first horizontal scan period, and supplied with a fourth image signal in the second horizontal scan period; a first scan line and a second scan line which are provided so as to be supplied with a selection signal in the first horizontal scan period; a third scan line and a fourth scan line which are provided so as to be supplied with a selection signal in the second horizontal scan period; a first pixel electrically connected to the first signal line, the second signal line, the first scan line, and the third scan line; a second pixel electrically connected to the first signal line, the second signal line, the second scan line, and the fourth scan line; a first shift register electrically connected to the first scan line and the fourth scan line; and a second shift register electrically connected to the second scan line and the third scan line, wherein each of the first pixel and the second pixel includes a transistor which includes an oxide semiconductor layer including a channel formation region, wherein the oxide semiconductor layer has crystallinity, and wherein the oxide semiconductor layer is a non-single-crystal film.
