Abstract
PURPOSE: To enhance the reliability of a liquid crystal display element in a positive type quest-host element of vertical orientation, by using a liquid crystal which becomes dielectrically positive at low frequencies and negative at high frequencies and driving display elements at high frequencies and nondisplay elements at low frequencies.
CONSTITUTION: The nematic liquid crystal added with the dichromatic dyes in which the frequency characteristics of te dielectric anisotropy of the liquid crystal become Δε>0 at the frequency f<fc and Δε<0 at the frequency f>fc with the crossover frequency fc at which the dielectric anisotropy Δε becomes 0 is grasped between a pair of transparent electrode plates which are disposed opposedly in a specified spacing and are vertically oriented at their inside surfaces. The display elements are so driven as to be applied with the waveforms comprising the frequency f>fc and the nondisplay segments to be applied with the waveforms comprising the frequency f<fc. Thereby, the temperature range and response speed may be improved and the dynamical driving is easy.
