Abstract
A pixel circuit may comprise: a first transistor having a first terminal connected to a data line and to which a data signal is applied and a gate terminal connected to a scan line and to which a scan signal is applied; a third transistor having a gate terminal connected to a second terminal of the first transistor and a second terminal connected to a light emitting device; a capacitor having a second terminal commonly connected to the second terminal of the first transistor and the gate terminal of the third transistor; and a second transistor having a second terminal commonly connected to a first terminal of the capacitor and a first terminal of the third transistor, a first terminal connected to a first power supply voltage, and a gate terminal connected to an emission line to which an emission signal is applied.
