ABSTRACT:
A liquid crystal device is constituted by a pair of substrates respectively having thereon a plurality of scanning lines and a plurality of data lines intersecting the scanning lines, and a liquid crystal disposed between the substrates so as to form a matrix of pixels each at an intersection of the scanning lines and the data lines. The liquid crystal device is driven under conditions that (1) the scanning lines are sequentially selected so that every N-th scanning line is selected in a field, (2) N is an odd number, (3) a period for selecting each scanning line is changed depending on an environmental temperature at which the device is placed, and (4) N is changed depending on the environmental temperature. As a result, a uniformly good image is displayed regardless of a temperature change and with minimum flicker liable to occur depending on a repetitive display pattern.
