Abstract
There is provided a display device including a display unit having pixels, each of which includes a luminescence element that individually becomes luminous depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a voltage signal, where the pixels are arranged in a matrix pattern. The display device includes a luminescence amount regulator for setting a reference duty for regulating a luminescence amount for each one frame, according to the input picture signal, and an adjuster for adjusting an effective duty that regulates, for each one frame, a luminous time for which the luminescence element is luminous, and a gain of the picture signal, based on the reference duty and the input picture signal, so that the luminescence amount is constant before and after adjustment.
