Abstract

PURPOSE: To secure the high-resolution picture dispaly and the color display by enclosing the smetic liquid crystal between two sheets of substrate containing the electrodes.
CONSTITUTION: Smetic liquid crystal layer 22 is held between transparent glass substrate 18 and 19 to which reflective electrode 20 formed by coating the reflective material and transparent electrode 21 are provided respectively. The lead terminals are drawn out from electrode 20 and 21 each, and switch 25 and power source 26 are connected to layer 22 for application of the electric field. In a display unit of such constitution, the liquid crystal surface is heated locally via writing heat source 23 used for the infrared semiconductor laser or the like to carry out the disply. At the same time, the reflective film is provided to electrode 20 to increase the heat writing efficiency as well as to enhance the reading contrast for observer 24. Furthermore, the color display becomes possible too with addition of the multiple color dyes into layer 22. Thus, the high-resolution display and the color display can be carried out.
