ABSTRACT:
A data signal line drive circuit supplying a video signal to a pixel array performs pseudo tone gradation processing with respect to the video signal that is sent to an n number of data signal lines SL by m (<n) stages of a pseudo tone gradation processing section, and outputs the video signal processed by the pseudo tone gradation processing section identical to the data signal lines SL per m lines when sends the video signals subjected to the pseudo tone gradation processing to the data signal lines SL. By doing this, the drive circuit using the pseudo tone gradation processing is given a simple circuit structure, thereby providing an image display apparatus of a driving circuit integrated type in which the pixel array and the drive circuit are formed on a substrate.
