Abstract
An image display device having a liquid crystal display panel in which display picture elements are arranged according to a dot matrix form includes a control circuit that controls the drive of a source driver and gate driver such that writing of signals for frame display in a horizontal direction is performed during the vertical blanking interval of input image signals. During the vertical blanking interval, the control circuit writes to the source driver each source selection signal of picture elements that are to display the horizontal frame and holds this data. The control circuit then generates sequential gate selection signals from the gate driver while supplying the held output of the source driver to the sources of the picture elements, and supplies horizontal frame display signals to the picture elements.
