Patent ID: 8830145

Claim:
A pixel circuit comprising: a light emitting element whose cathode is connected to a first power source for supplying a first power supply voltage; a first transistor that has a first terminal connected to a data line and is selectively conducted with a voltage applied to a gate terminal; a second transistor that is connected between the gate terminal of the first transistor and a second terminal of the first transistor and is selectively conducted in response to a first scan signal applied to a gate terminal; a third transistor that is connected between the second terminal of the first transistor and an anode of the light emitting element and is selectively conducted in response to a light emission control signal applied to a gate terminal; a fourth transistor that is connected between the gate terminal of the first transistor and an initialization power source and is selectively conducted in response to a second scan signal applied to a gate terminal; and a capacitor element, one end of which is connected to a power source for supplying a voltage having a fixed potential and the other end of which is connected to the gate terminal of the first transistor, wherein, during a non-light emission period of one frame in which the light emitting element emits no light, a data signal is applied to the data line, and during a light emission period of one frame in which the light emitting element emits light in response to the data signal, a second power supply voltage having a higher potential than the first power supply voltage is applied to the data line.
