Liquid crystal display device

Abstract

Abstract PURPOSE:To obtain a liquid crystal display of the positive display system which has a high contrast and a high display quality, by giving horizontal and vertical compound arranging properties to one electrode substrate and giving a horizontal arranging property to the other electrode substrate facing said electrode substrate. CONSTITUTION:A liquid crystal layer with nematic liquid crystal molecules 14 having the positive dielectric anisotropy as the host and bicolor dye 15 as the guest is held between transparent substrates 11a and 11b having transparent electrodes 12a and 12b to constitute a nematic liquid crystal display. A part 13a-2, which has the horizontal arranging property, corresponding to a display pattern part and a part 13a-1, which has the vertical arranging property, corresponding to a background are formed as an arrangement control layer on the transparent substrate 11a, and an arrangement control layer 13b having the horizontal arranging property is formed on all of the surface of the transparent substrate 11b. Arrangement directions of arrangement control layers 13a-1 and 13b are orthogonal to each other. The polarization direction of a deflector 13 and the horizontal arrangement direction near the substrate 11a are made parallel with each othr to obtain a high-contrast and deep colored display pattern on a colorless bright background.
