Abstract
There is disclosed an active matrix liquid crystal display that suppresses formation of a stripe pattern on the displayed image. An active matrix circuit, a peripheral drive circuit, and A image data signal lines for supplying image data signals are all integrated on a common substrate. The liquid crystal display includes a sampling circuit to which sampling circuit input lines are connected. These sampling circuit input lines are in contact with the image data signal lines and include dummy conducting lines extending to a buffer circuit. These dummy lines average out impedances of the individual image data signal lines, thus making uniform the amounts of image data signals lost from the image data signal lines. Thus, the formation of the stripe pattern is suppressed.
