Patent ID: 8344971

Claim:
An image display device having a display portion formed by disposing pixel circuits in a matrix, and a signal line driving circuit and a scanning line driving circuit for driving said pixel circuits through signal lines and scanning lines of said display portion, said pixel circuit comprising: a light emitting element; a drive transistor for current-driving said light emitting element; a hold capacitor; and a write transistor adapted to be turned ON/OFF in accordance with a write signal outputted from said scanning line driving circuit, for setting a voltage developed across terminals of said hold capacitor at a voltage of corresponding one of said signal line; wherein said signal line driving circuit alternately outputs a signal voltage, and a fixed voltage, wherein an amplitude of the write signal is increased as compared with a case where the voltage developed across said terminals of said hold capacitor is set at the signal voltage, to turn OFF said write transistor, for making the voltage developed across said terminals of said hold capacitor variable from the fixed voltage.
