ABSTRACT:
A liquid crystal device of a matrix type, having a pair of electrode substrates disposed in spaced opposition to each other, with a liquid crystal, such as a ferroelectric liquid crystal, in the space between the substrates, which provides improved display quality. A group of scanning signal lines and a group of information signal lines are arranged on the mutually opposing surfaces of the substrates, and extend perpendicular to each other. In one form of the present invention, the scanning signal lines have a smaller resistance than the information signal lines. In another form, the scanning signal lines have a smaller resistance to the input thereto than the information signal lines. Thus, the peak value of ripple on the scanning signal lines, hence, the influence of the ripple on the non-select pixels, is reduced, thereby eliminating flickering on the screen caused by the ripple.
