Abstract

A display device includes a display panel including a plurality of pixels and a power line, and displaying an image in a normal mode or a power saving mode, a data driver which provides a data signal to the pixels, and a power supply which supplies a source driving voltage to the data driver and supplies a first power voltage to the power line in the normal mode. The data driver supplies a first auxiliary power voltage to the power line in the power saving mode, and the power supply outputs the first power voltage by decreasing a voltage level of the first power voltage to a first power saving voltage level in a vertical blank period in which the pixels do not display an image during a first switching period changing from the normal mode to the power saving mode.
