ABSTRACT:
A color liquid crystal display device includes a pair of oppositely disposed substrates each of which is provided with an electrode and has been subjected to homeotropic alignment treatment, and chiral nematic liquid crystal disposed between the pair of oppositely disposed substrates. The chiral nematic liquid crystal is capable of causing birefringence leading to a change in brightness and a change in hue depending on a voltage applied between the electrodes. The liquid crystal is twistedly aligned under electric field application to change a twisted angle, so that a fluctuation in birefringence with temperature is compensated.
