PURPOSE:To obtain a bright color display without using color filters, to widen visual field angles and to lessen color changes of display colors by temp. CONSTITUTION:Polarizing plates 21, 22 are arranged across a liquid crystal cell 10 where liquid crystal molecules are twist oriented. A biaxial phase difference plate 23 having a refractive index nx in an x-axis direction which is a delay axis phase, a refractive index ny in a y-axis direction and a refractive index nz in a z-axis direction in a relation nx>nz>ny is arranged between the front side polarizing plate 21 and the liquid crystal cell 10. The directions of the transmission axes of the polarizing plates 21, 22 and the delay axis of the phase difference plate 23 and the orienting direction of liquid crystal moleculates near the substrate of the liquid crystal cell 10 are so set that the respective wavelength light rays of the incident light after transmitting the front side polarizing plate 21 are made into elliptically polarized light rays of the respectively different polarization states by the double refractive effect of the phase difference plate 23 and the double refractive effect of the liquid crystal layer 18 of the liquid crystal cell 10 and that the light quantity ratios of the respective wavelength light rays of the light transmitted through the rear side polarizing plate 22 among these light rays attains the ratios corresponding to the desired colored light rays.
