Abstract: According to one embodiment, a display device includes substrates with pixels, a pixel electrode in each of the pixels, a display select circuit connected to the electrode, which supplies display and non-display voltages, a power line to which first and second voltages are supplied, a memory device connected to the power line and the display select circuit, a voltage select circuit which selects a voltage to be supplied to the power line from the first and second voltages, and a clock circuit which generates a clock signal. The memory device controls the display select circuit using the first and second voltages, and the first voltage select circuit selects the first or second voltages in synchronism with the clock signal.
