Abstract
A display device includes at least display elements arranged in a two-dimensional matrix, data lines provided for respective display element columns, and a source driver that supplies a video signal voltage to the data lines, in which a display element row includes a display element belonging to a first group and a display element belonging to a second group different from the first group, the source driver includes a ramp signal generating circuit and a switch circuit that causes a data line to hold a video signal voltage, and when output of the ramp signal generating circuit and a data line are switched from a connected state to a disconnected state in order to cause the data line corresponding to a certain display element to hold a video signal voltage, a data line corresponding to a display element belonging to a group different from the group, to which the certain display element belongs, and output of the ramp signal generating circuit are switched from the disconnected state to the connected state.
