Abstract

PURPOSE: To provide a liquid crystal display device which increases scattering brightness and is stably operated by DC square wave voltage driving, by incorporating a cyano compd., in which the molecular structure is unsymmetrical and the main skeletal structure is a resonance structure, into a nematic liquid crystal compd.
CONSTITUTION: In a liquid crystal display device employing a nematic liquid crystal compd. (Nn liquid crystal) in which the dipole noment direction of the molecule is approximately perpendicular to the direction of the long axis of the molecule; a cyano compd., in which the molecular structure is unsymmetrical and the skelton of the molecular structure is a resonance structure such as an arom. ring or ethylene bond such as tricyanoethylene of formula I or 11,11-dicyanonaphthoquinomethane, is incorporated into said liquid crystal compd. By this incorporation, there is obtd. the desired liquid crystal display device which is improved so as to increase scattering brightness and stably operate with DC square wave voltage driving.
