Abstract:
Provided is a display device that can sufficiently secure a period for threshold value detection with a simple configuration and that can inhibit occurrence of luminance non-uniformity. The display device includes a plurality of pixel circuits; a gate driver circuit connected to a plurality of scanning signal lines and a plurality of control lines; and a power control circuit connected to a plurality of power lines through a common power line. Each pixel circuit includes an organic EL element, a plurality of TFTs, and a capacitor. During each frame period, after initialization and threshold value detection are collectively performed on a plurality of rows, writing and light emission are performed sequentially on a row-by-row basis. Here, in a preceding frame (first frame) of two consecutive frame periods, writing is performed in order from the first row to the nth row (ascending order). In a subsequent frame (second frame) of the two frame periods, writing is performed in order from the nth row to the first row (descending order).
