ABSTRACT:
Display device wherein change of the amount of light of the light-emitting elements caused by change of the number of light-emitting elements that emit light simultaneously is small. This display device includes a display panel having light-emitting elements arranged in matrix fashion; data lines for applying anode potential to light-emitting elements of the same column; scanning lines for applying cathode potential to light-emitting elements of the same row; and a control circuit that adjusts voltage between the anode and cathode of the light-emitting elements based on the number of light-emitting elements that emit light simultaneously. The control circuit suppresses changes of voltage between the anode and cathode of the light-emitting elements caused by a change in the number of light-emitting elements that emit light simultaneously. Accordingly, change of the amount of light of the light-emitting elements is suppressed.
