Patent attributes
An object of the disclosure is to achieve a current-driven display device able to compensate for a variation in threshold voltage of a drive transistor without causing a variation in luminance. A pixel circuit includes an organic EL element; a drive transistor; a first capacitor having a first electrode to be supplied with a reference voltage during a data writing period and a second electrode to be supplied with a data voltage-during a data writing period; a second capacitor having a first electrode connected to the first electrode of the first capacitor and a second electrode connected to a first conduction terminal of the drive transistor; and a short-circuit control transistor having a gate terminal to be supplied with a light emission control signal-, which becomes active during a light emission period, a first conduction terminal connected to the first electrode of the first capacitor, and a second conduction terminal connected to the second electrode of the first capacitor.
