Abstract

This invention is directed to provide a driving method capable of reducing the sticking and after-image of a picture resulting from the change of characteristics of a switching device due to a current in a two-terminal type active matrix liquid crystal display device. The liquid crystal display device includes a plurality of data lines and scanning lines, and liquid crystal pixels so disposed as to correspond to points of intersections between the data lines and the scanning lines. The liquid crystal pixel has at least one two-terminal type switching device, and is driven by a scanning signal applied to the scanning line and a data signal applied to the data line. Here, a period (27, 28, 32, 33) in which a current is supplied through the switching device is disposed before a selection period (26, 31) of the scanning signal Ζ(n). Further, a retention period is disposed after the selection period.
