Patent ID: 8269697

Claim:
An image display device comprising: a display section including pixel circuits in a form of a matrix, the pixel circuits each including: a light emitting element; a switch transistor; a driving transistor for current-driving the light emitting element by a driving current corresponding to a gate-to-source voltage of the driving transistor via the switch transistor; a storage capacitor for retaining the gate-to-source voltage; and a writing transistor for setting a terminal voltage of the storage capacitor by a voltage of a signal line, wherein an emission period during which the light emitting element is made to emit light and a non-emission period during which light emission of the light emitting element is stopped are alternately repeated, in the non-emission period, after a voltage across the storage capacitor is set to a voltage more than a threshold voltage of the driving transistor, the voltage across the storage capacitor is set to a voltage corresponding to the threshold voltage of the driving transistor, the terminal voltage of the storage capacitor is set to the voltage of the signal line, whereby light emission luminance of the light emitting element in the next the emission period is set, and the switch transistor is set in an off state during the non-emission period, the voltage across the storage capacitor is set to the voltage more than the threshold voltage of the driving transistor by lowering a drain voltage of the driving transistor and setting the terminal voltage of the storage capacitor by the signal line via the writing transistor.
