Patent ID: 7463224

Claim:
A light emitting device comprising: a driver transistor provided between an emissive element and a power supply, for controlling supply of power from the power supply to the emissive element to drive the emissive element; a control transistor for receiving a digital data signal corresponding to emission information on a gate and for controlling whether or not to fix a gate potential of the driver transistor to a predetermined potential based on the digital data signal; and a control capacitor connected between a gate of the driver transistor and a control line to which a control pulse signal for controlling a light emission period of the emissive element is supplied, wherein the gate of the driver transistor is connected to a conductive region of the control transistor which is not connected to the gate of the control transistor, and during the light emission period defined by the control pulse signal, the gate potential of the driver transistor is controlled to be shifted or not shifted to a potential corresponding to the control pulse signal based on the digital data signal supplied to the gate of the control transistor and a supply operation of power through the driver transistor to the emissive element is controlled.
