Abstract
PURPOSE:To obtain a steep threshold characteristic in the state in which striped domains are hardly generated by adding an adequate ratio of specific compds. in place of CB-15, CN (cholesteryl nonanoate) as a cholesteric liquid crystal (chiral nematic liquid crystal) to be added to a nematic liquid crystal to said liquid crystal. CONSTITUTION:The value of the angle phi at which the molecular orientation bearing of the liquid crystal is set in a 200<=phi<=290 deg. range and the ratio d/p of the spiral pitch (p) of the liquid crystal molecules and the layer thickness (d) of the liquid crystal cell is set in a (phi/360 deg.-1/4)<d/p<phi/360 deg. range. The nematic liquid crystal contains at least >=1 kinds among the compd. groups expressed by formula I, formula II, etc. In formulas I, II, H denotes a cyclohexane ring and R1-R33 denote an alkyl chain of 2-15C. The steep threshold value characteristic in the state in which the striped domains are hardly generated is thereby obtd. to the extent that this device is applicable to a panel.
