PURPOSE:To obtain a liquid crystal display device which has a wide visual field angle, superior visibility, and small color shade and is low in manufacture cost by using a liquid crystal compound obtained by incorporating p type dichroic dye in liquid crystal. CONSTITUTION:This device is equipped with a liquid crystal cell having a molecule orienting film 4 which twists and orients the liquid crystal 3 by >=180 deg. angle and polarizing plates 6 arranged in front of and behind the liquid crystal cell opposite each other. Then the liquid crystal 3 is the liquid crystal compound contg. p type dichroic dye. The transmissivity corresponding to 500nm wavelength with which thin green is obtained is decreased by adding the characteristic absorption band 500nm of the dye and the transmission spectrum becomes flat on the whole. Thus, an achromatic color is employed as a background color to improve the visibility and the added dye exerts no influence upon the visual field angle, which is therefore widened.
