Abstract

PURPOSE:To prevent the dielectric breakdown of liquid crystal layers without color irregularity and to permit accurate reading, etc. of displays by arranging spacers that hold the spacing between transparent electrodes constant on the surfaces of the transparent electrodes or transparent substrates. CONSTITUTION:In a liquid crystal display device wherein transparent substrates 1, 2 consisting of, for example, glass plates, vapor deposited or coated with transparent electrodes 3, 4 on the inside surfaces are disposed oppositely a dynamic scattering effect type liquid crystal material 7 and spacers 6 are inserted between the electrodes 3 and 4, and a sealing member 5 for preventing the outflow of the material 7 to the outside is provided on the circumference between the substrates 1 and 2, the spacers 6 which maintain the spacing between the electrodes 3 and 4 uniformly and are made by solidfying transparent or opaque powder of, for example, glass fibers with frit glass are provided like patterns of a scale. When voltage is applied between the electrodes 3 and 4, the color irregularity and the dielectric breakdown does not occur, and in the case of using this as a projection screen, the projected images are read accurately.
