Abstract
There is provided an image display apparatus having light emitting elements in its pixels, producing high resolution, facilitating γ correction, and free from occurrence of pseudo contours. A pixel circuit of the image display apparatus of the present invention with a switch circuit for switching between two states of supply and cutoff of a current to the light emitting element, a preset circuit for presetting the switch circuit at one of the two states independently of an analog display voltage signal, and a reset circuit for reversing the one of the two states of the switch circuit based upon the analog display voltage signal.

An image display apparatus comprising
- a plurality of pixels disposed on a substrate, and
- a plurality of signal lines disposed on said substrate for inputting an analog display voltage signal into each of said plurality of pixels,
- wherein
- each of said plurality of pixels is provided with a light emitting element with light intensity thereof varying with a current therethrough, and a pixel circuit for driving said light emitting element, and
- said pixel circuit is provided with switch means for switching between two states of supply and cutoff of a current to said light emitting element, preset means for presetting said switch means at one of said two states independently of said analog display voltage signal, and reset means for reversing said one of said two states of said switch means based upon said analog display voltage signal.
