Abstract
A pixel circuit including a light emitting element outputting a gray scale based on a current supplied thereto, a first transistor configured to control an amount of current supplied to the light emitting element based on a gray scale data voltage supplied to a gate electrode of the first transistor, a second transistor connected between the gate electrode of the first transistor and an initialization voltage, a third transistor connected between the gate electrode of the first transistor and a first terminal of the first transistor; a fourth transistor connected between the first terminal of the first transistor and the light emitting element, and a fifth transistor connected between a second terminal of the first transistor and a data line. The data line is selectively supplied with the gray scale data voltage and a power supply voltage for light emitting of the light emitting element to the fifth transistor.
