PURPOSE: An LCD equipped with non-specular reflector is provided not to relate the incident light specularly with the reflected light passing the display. CONSTITUTION: The incident light enters the display at the angle in a prescribed range while the reflected light, namely the visible direction, is controlled to a right or near a right angle to the display. The angle of a polarizing plate, input/output director of a liquid crystal cell and retardation of the liquid crystal cell of the non-specular LCD should be specially optimized to obtain the optimum visual effect. A conventional LCD mode does not function as the optimum in the non-specular state. A non-specular LCD with a new image mode and a shadow mode is obtained by this method. The display has an extremely bright background and no visible glare which is almost general for any LCD. The method can be used for all twist angles in a 90deg. TN, 120°C and 150°C HTN, and 180deg., 240°C and 270°C STN display or the like.
