Abstract
Disclosed herein is an image display device including a display section formed by arranging pixel circuits in a matrix form. Each pixel circuit includes at least a light emitting element, a drive transistor, a holding capacitor, and a write transistor. A light emission and non-light emission periods are alternately repeated. A light emission period start voltage and a non-light emission period start voltage are alternately output to the signal line. The terminal voltage of the holding capacitor is set to start the light emission and non-light emission periods. The write signal is set to sequentially delay the timings. The power drive signal is set in units of a plurality of successive lines. The drain voltage of the drive transistor is pulled up to high level at a time other than when the one of the terminals is connected to the signal line by the write signal in different lines.
