Abstract: According to an aspect, a display device includes an image display panel including: sub-pixel rows, in each of which sub-pixels for displaying different colors are periodically arrayed in a first direction, are regularly arranged in a second direction different from the first direction; signal lines in parallel to sub-pixel columns in which the sub-pixels are successively arranged in the second direction; and scan lines that sequentially select each sub-pixel row. Each of m (integer≥2) selector signals selects n (integer 1) pairs of the signal lines each supplied with two signals each having a mutually reverse polarity, within a period during which each sub-pixel row is selected by a corresponding scan line, and a sum of potential changes of the n pairs of the signal lines selected by each selector signal is substantially zero when each sub-pixel row is sequentially selected by the corresponding scan line.
