Patent ID: 8411079

Claim:
A light-emitting device, comprising: a scanning line; a data line; a pixel circuit arranged corresponding to an intersection of the scanning line and the data line; and a power source line, the pixel circuit including: a light-emitting element; a driving transistor connected between the power source line and the light-emitting element; a first switching transistor connected to the data line; a second switching transistor connected between a gate and a source of the driving transistor; and a capacitance connected between the first switching transistor and the gate of the driving transistor, during a first period, the first and second switching transistors being turned on, and a reference potential being supplied to the data line; and during a second period, the first switching transistor being turned on, and the second switching transistor being turned off, and a data potential corresponding to light-emitting brightness of the light-emitting element being supplied to the data line, and a potential of the power source line being at a low level; and during a third period after the second period, the first and second switching transistors being turned on and the data potential being supplied to the data line, and a potential of the power source line being at the low level.
