Claim Text:
1. A pixel circuit, comprising: a light emitting element to emit a gray scale of light based on a current supplied thereto; a first transistor 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 to which the gray scale data voltage and a power supply voltage for light emitting of the light emitting element are selectively supplied, wherein: a first field in which the gray scale data voltage is supplied to the data line and a second field in which the power supply voltage for light emitting of the light emitting element is supplied to the data line are alternated in turn, the third transistor is controlled by a gate control signal and the fifth transistor is controlled by a first emission control signal, and during the first field, the third transistor and the fifth transistor are turned on in response to the gate control signal and the first emission control signal such that the gray scale data voltage is supplied to the gate electrode of the first transistor, and then, the third transistor is turned off in response to the gate control signal.
