Abstract
PURPOSE: To provide a liquid crystal display device which has a long life and in which a liquid crystal and a dichromatic coloring matter are not deteriorated by ultraviolet light, by using a liquid crystal compsn. contg. an ultraviolet absorber blended therewith.
CONSTITUTION: 0.05W5wt% benzotriazole ultraviolet absorber of formulaI [wherein R1 is H, Cl; R2 is H, C(CH3)3, C(CH3)2C2H5]and/or benzophenone ultraviolet absorber of formula II (wherein R is a 1W8C alkyl) are/is blended with a nematic liquid crystal contg. a dichromatic coloring matter added thereto. Then a display device is formed by using the resulting liquid crystal compsn.
