Tolan compound and liquid crystal composition containing the same |
| abstract |
A novel tolan compound of the formula (I): <IMAGE> (I) wherein A is a substituted or unsubstituted cyclohexyl or phenyl group; B is -CO-O- or -O-CO-; X is a hydrogen atom, a halogen atom, a cyano group, a C1-C10 alkyl group, or a C1-C10 alkoxy group; Y is a hydrogen atom or a halogen atom; and m and n are an integer of 0 or 1, provided that m+n=0 or 1. The tolan compound can raise the N-I point and increase the double refractive index ( DELTA n) of liquid crystal compositions. The liquid crystal composition containing this tolan compound has excellent characteristics as a liquid crystal material, and the liquid crystal display device using this liquid crystal composition has a wide temperature range and a wide visible angle and can be operated at a low driving voltage. |
