A gate driver circuit for driving an active matrix LCD device is adapted to a mutli-scan function. The gate driver circuit includes a memory circuit including a plurality of (N) memory cells each disposed for a corresponding one of gate lines in the LCD device, a scan circuit including N transfer elements, and a gate line drive circuit including N logic units effecting a specific logic operation. The logic units consecutively drives gate lines in the central area in the picture writing period for displaying a picture image, and drives gate lines in the top and bottom peripheral areas at once for displaying black color. The LCD device displays the picture image on the central area on a selected number of pixel elements for adapting an image source.
