Abstract
In an organic EL display device including a proximity sensor, deterioration in display quality due to irradiation with IR light is suppressed. In a display period during which an image is displayed on a display unit, an emitting unit of the proximity sensor emits the IR light only in a period including a part of an IR light irradiation region turn-off period during which a plurality of light-emission control lines are driven such that no current is supplied to each of organic EL elements included in pixel circuits in a row corresponding to the IR light irradiation region, the period being before a time point at which the writing of a data signal into each of the pixel circuits in each of rows corresponding to the IR light irradiation region is started.
