Abstract

PURPOSE:To obtain a negative liq. crystal display device of phase transition type with a variety of colors and fine decorative properties by adding a dye to a liq. crystal and applying a voltage to a display pattern part alone to carry out a display at a transparent state with a background of a light scattering state. CONSTITUTION:Transparent electrodes 5 are provided on each glass substrate 4. Each spiral 6 shown that a mixed liq. crystal is at a cholesteric state having the spiral axis in the direction of the line in spiral. Thick rods 7 are a dichromatic dye, thin rods 8 show a nematic state of the liq. crystal, and a light scattering state due to a thermooptical effect is shown by 9. In addition, 10 shows a light scattering state of a focal conic state formed by applying a low voltage, and 11 shown a homeotropic state formed by applying a high voltage. The light scattering states of 9, 10 are similar to each other in appearance including coloring degree due to the dye to form an erasing state. The transparent part of 11 is not colored since the dye is oriented in the direction of weak light absorption by the orientation of the liq. crystal.
