Abstract
Provided is a display device including: a control portion; a display panel including one or more pixel circuits and an image signal line connected to the pixel circuits; and an image signal line driving circuit. The control portion includes a difference acquiring circuit for acquiring difference data between a value of a gray-level potential, which is to be applied to one of the pixel circuits from the image signal line, and a value of a precharge potential based on the gray-level potential. The image signal line driving circuit calculates the precharge potential based on the value of the gray-level potential and the difference data, and supplies the image signal line with the precharge potential and the gray-level potential in sequence.
