A display device includes a display panel unit configured to include pixel circuits in each of which an organic electroluminescence device is used as a light emitting device and is driven to emit light with luminance dependent upon a voltage difference between a signal value voltage of an input display data signal and a signal amplitude reference voltage. The display device further includes: a voltage controller configured to carry out grayscale value detection for a display data signal to be supplied to the display panel unit in every predetermined period, and create voltage control information of the signal amplitude reference voltage by using a detected grayscale value; and a signal amplitude reference voltage changer configured to change a voltage value of the signal amplitude reference voltage to be supplied to the pixel circuits of the display panel unit, based on voltage control information created by the voltage controller.
