Abstract

PURPOSE:To enable color display with a good color balance by changing the thicknesses of liquid crystal layers corresponding to respective color filters according to colors so that the threshold values of respective colors coincide. CONSTITUTION:This display element is constituted of an upper polarizing plate 1, a liquid crystal cell (display cell) 2 which makes display, a liquid crystal cell (compensation cell) 3 as an optically anisotropic body and a lower polarizing plate 4. The color filters 9 of the display cells 2 are formed by a method for impregnating dyes into gelatin films. The thicknesses of the filters are changed by colors by utilizing the swelling arising from dye impregnation so that the thicknesses dR, dG, dB of the liquid crystal layers 8 corresponding to the color filters 9 of colors; red, green and blue, are respectively set to 5.95mum, 6.0mum, 6.05mum. The color liquid crystal display element having the good balance is obtd. by equalizing the threshold values of the electro-optic characteristics by colors in such a manner.
