Patent ID: 7042431

Claim:
An image display device, comprising: a plurality of pixels disposed in a matrix form; a plurality of data signal lines disposed in respective columns of the pixels; a plurality of scanning signal lines disposed in respective rows of the pixels; a data signal line drive circuit for driving said plurality of data signal lines by outputting thereto a signal potential in synchronization with a predetermined timing signal; a scanning signal line drive circuit for driving said plurality of scanning signal lines by outputting thereto a scanning signal in synchronization with a predetermined timing signal; a display section including said plurality of pixels, scanning signal lines and data signal lines, for displaying an image based on a video signal inputted to the data signal line drive circuit; and a pre-charging circuit for supplying a predetermined pre-charge potential to said plurality of data signal lines according to the pre-charge control signal from an external section at a predetermined interval, wherein in a vertical retrace interval, the pre-charge potentials of positive and negative polarities are each supplied in a lump sum to said data signal line from said pre-charging circuit at least once.
