Abstract

PURPOSE:To make a high-speed and uniform display possible, by setting the torsion angle of the arrangement of liquid crystal molecules between two electrode substrates to an angle larger than 90 deg. and smaller than 130 deg. to prevent the direction of the inclination from being inverted by the rotation of liquid crystal molecules. CONSTITUTION:Electrode faces facing to each other of upper and lower electrode plates 1 and 2 are subjected to the orientation treatment so that directions of orientation of upper and lower electrode plates make an angle of 90-130 deg., for example, to 100 deg.. In this case, the honogeneous orientation is obtained where longer axes of liquid crystal molecules 3 are arranged in the direction of an arrow in the direction of the tip of the arrow. In a liquid crystal 9, optically active substance.4-cyanogen.4'-(2-methyl).butyl-biphenyl which induces the left torsion in a positive dielectric anisotropic nematic liquid crystal is added. The torsion angle of molecules 3 becomes 100 deg., and an inclination angle theta of molecules 3 to electrode plates 1 and 2 becomes uniform in accordance with the torsion.
