Abstract
Provided is an OLED display device preventing an occurrence of a crosstalk using a simple structure. A display device includes: a display unit that includes a plurality of pixel circuits each including an organic light emitting element; a control unit that applies electric potential to the pixel circuits for a first period, and that controls emission luminance of the organic light emitting elements for a second period after the first period; and an application unit that applies a voltage of less than or equal to a threshold voltage of the organic light emitting element before a start of the second period in which the organic light emitting element has internal capacitance to maintain an electric potential difference between the anode electrode and the cathode electrode for a vertical scanning period in which a displayed image to be refreshed when the control unit controls the organic light emitting element not to emit light.
