Abstract

PURPOSE: To provide a low-voltage type liquid crystal display device with a low operation voltage suitable for a watch or the like, by sealing a liquid crystal composition containing one or more of specified 2, 3-dicyanohydoquinone derivatives between transparent base plates equipped with transparent electrodes.
CONSTITUTION: One or more of 2, 3-dicyanohydroquinone derivatives shown by formula I (wherein X is a group shown by formula II or III, Y is a group shown by formula IV or V, R1 and R3 are 1W10C alkyl or alkyloxy) is added to a liquid crystal of which dielectric anisotropy is negative such as an azoxy type liquid crystal, a phenoxycarbonylbenzene type liquid crystal or a biphenyl type liquid crystal to prepare a liquid crystal composition. Subsequently, said liquid crystal composition is sealed between two base plates at least one of which is transparent equipped with transparent electrodes to produce the objective liquid crystal display device.
