Abstract
A pixel circuit of a display device Includes: an electro-optical element; a drive transistor; a write control transistor; a threshold compensation transistor; two light emission control transistors; a first initialization transistor having a first conduction terminal connected to a gate terminal of the drive transistor, a second conduction terminal to which an initialization voltage is applied, and a gate terminal connected to a first initialization control line; and a capacitor provided between a first conductive member and the gate terminal of the drive transistor. In a non-light emission period, time during which a voltage of the first initialization control line is at an on-level is longer than a period during which a voltage of a scanning line is at the on-level. As a result, a display device capable of sufficiently initializing the gate terminal of the drive transistor is provided.
