Abstract
An active matrix liquid crystal display consuming only a small amount of electric power. The liquid crystal display has two driver circuits which drive two sets of signal lines, respectively, One set of signal lines creates the upper half of a frame of image displayed on the viewing screen, while the other set of signal lines creates the lower half of the image. An image signal for creating the frame of image is supplied to the two driver circuits alternately so that when one of the driver circuits is operating, the other is halted or put on standby.
