PURPOSE:To obtain a device which does not require a photoprocess, is simple to produce and has good display quality by forming a color filter of a thin thermosensitive coloring film of an optical writing type and forming the filter in such a manner as to have the patterns of the colors matching the patterns of picture element electrodes. CONSTITUTION:The color filter is formed of the thin thermosensitive coloring film of the optical writing type. The RGB color pattern regions 29, 30, 31 of the color filter are formed in the same position and to the same shape as the positions and shapes of the picture element electrodes 241, 242, 243 facing said regions. The regions where there are no picture element electrodes facing said regions are transparent. An AC voltage 32 is impressed between the electrodes 23 and 241 to orient vertically the dye molecules within the CH liquid crystal in the region sandwiched by these picture element electrodes. The molecules are held horizontally oriented in the other regions. White light 34 is made incident vertically to the substrate in this state via a polarizing plate 33, then the light incident to the electrode 241 transmits the liquid crystal layer and the red pattern 29 of the color filter and is taken out to the substrate 21 side. The light incident to the other regions is all absorbed into the black dye in the GH liquid crystal. |
