Abstract
A method is provided for driving an active matrix substrate including a plurality of signal lines provided on an insulator substrate along a first direction, a plurality of scanning lines provided along a second direction to intersect the plurality of signal lines, a plurality of pixel electrodes provided at the intersections of the plurality of signal lines and the plurality of scanning lines, and a plurality of common electrodes provided to form a storage capacitor between each common electrode and the corresponding pixel electrode, a semiconductor layer being provided between each common electrode and the corresponding pixel electrode. The method includes the step of applying a signal to each common electrode such that the depletion layer formed in the semiconductor layer has the maximum width.
