Abstract

PURPOSE: To obtain a peculiar coloration by mixing an interference color and an absorption color together, with a reflecting type colored liquid crystal display device using a 45 degrees twist cell in which a positive dielectric anisotropic liquid crystal is enclosed, by using a color phase difference plate.
CONSTITUTION: Black and white polarizing plate 11 is installed between observers and 45 degrees twist liquid crystal cell 12, and color phase difference plate 13 using a dichroism dye is installed between reflecting plate 14 and liquid crystal cell 12. Color phase difference plate 13 is arranged so that the polarization axis of light passed through cell 12 under OFF condition may coincide with the orientation direction of dichroism dye. At the above mentioned device, a light absorption of dye molecules occurs strongly and a color produced by the light absorption, which is peculiar to the dye, is displayed under OFF condition, and a mixed color of interference coloration produced by the phase difference of color phase difference plate and absorption coloration produced by the dye molecules (a total of 50% of absorption takes place because it obliques with the polarization axis of polarized light for an angle of 45 degrees) is displayed under ON condition.
