Abstract

PURPOSE: To provide a composition for liquid crystal color display, having excellent light resistance, and exhibiting clear orangeWblue color and extremely good dichroism, by dissolving a dichroic dye composed of an anthraquinone compound having a specific structural formula in a liquid crystal.
CONSTITUTION: The objective composition is obtained by dissolving (A) a dichroic dye composed of an anthraquinone compound of formula (R1WR3 are H, amino, OH, nitro or halogen; AlK is halogen, cyano, OH, phenyl, etc.; R4 is H, halogen, cyano, OH, 1W4C alkyl or Alk; X is halogen or 1W4C alkyl; m is 1 or 2; n is 0, 1 or 2) in (B) a liquid crystal (e.g. a nematic liquid crystal composed of a mixture of 43% 4-cyano-4'-n-pentylbiphenyl, 17% 4-cyano-4'-n- propoxybiphenyl, 13% 4-cyano-4'-n-pentoxybiphenyl, etc.). The concentration of the dye in the liquid crystal is preferably 0.01W5%.
