ABSTRACT:
In a method for driving a liquid crystal display device in which a scanning electrode signal and a data electrode signal are successively applied to a display panel where picture elements, which are arranged so that a liquid crystal element and a two-terminal non-linear element are connected in series, are arranged in a matrix-like pattern, a scanning electrode signal whose level is switched to a higher and lower levels than a reference level is applied during the selecting period for determining as to whether the picture element is turned on or off and a scanning electrode signal with the reference level is applied during non-selecting period. As a result, production of a residual image and occurrence of crosstalk can be lowered.
