Abstract

PURPOSE: A display device of guest host type liquid crystal having improved display contrast characteristics, obtained by using a biphenyl compound of liquid crystal having a specific structure as a material of liquid crystal and a tetrabin compound having a specified structure as a dichromatic dye-stuff material.
CONSTITUTION: A display device of liquid crystal of guest host type, comprising a tetrabin compound shown by the formula II (R and R' are alkyl) as a dichromatic dye-stuff dissolved in a biphenyl compound of liquid crystal shown by the formula I (R is alkyl) sandwiched by two electrodes, utilizing a twist nematic orientation which displays by causing the orientation deformation of a liquid crystal molecule through the impression of electric field so that the degree of the light absorption of the dyestuff is changed.
