Patent ID: 8508562

Claim:
An image display device comprising: a plurality of pixels; a signal line for inputting a display signal to the plurality of pixels; a power supply line for supplying power to the plurality of pixels; each of the plurality of pixels including a first transistor which have a source and a drain one of which is connected to the power supply line and which controls light emission of corresponding one of the plurality of pixels, a second transistor arranged between the drain of the first transistor and a gate thereof, a third transistor which have a source and a drain one of which is connected to the other of the source and the drain of the first transistor, a light emitting device connected to the other of the source and the drain of the third transistor, and a capacitor which have a first end connected to the signal line and a second end connected to the gate of the first transistor; a first voltage applying circuit for inputting the display signal to the first end of the capacitor in each of the plurality of pixels during write period in order to store a potential difference on the capacitor in accordance with the display signal and a threshold voltage of the first transistor in corresponding one of the plurality of pixels; a second voltage applying circuit for inputting a predetermined voltage to the first end of the capacitor in each of the plurality of pixels during light-on period.
