Abstract

According to one embodiment, a display device, includes a first pixel line including a first sub-pixel and a second sub-pixel, a second pixel line including a third sub-pixel and a fourth sub-pixel, and a display driver supplying video signals which cause signal polarities of signal lines adjacent to each other to be opposite to each other, without varying the polarities in one frame period, the video signals having the same polarities as each other being written to the respective sub-pixels of the first pixel line, the video signals having the polarities which are the same as each other and opposite to the polarities of the video signals written to the first pixel line, being written to the respective sub-pixels of the second pixel line.
