A liquid crystal display according to the invention includes one LCD module (10) with polarizers (12, 13) on both sides thereof. To generate the picture for the LCD module the display includes a control unit (18) to control the electric current to the electrodes of the module. The display additionally includes, in a known manner, reflector surfaces (14, 15) to reflect rays of light into the viewing direction through the polarizers and LCD module. The display may further include light guides (16, 17) placed between the polarizers and reflector surface to provide a backlight for the display. In a liquid crystal display according to the invention the reflector surfaces are placed on opposing sides of the LCD module. Thus there is provided in one and the same LCD module sub-displays (22, 23) viewable from opposing directions on different sides of the LCD module. The reflector surfaces can be made fixed in the liquid crystal display or a reflector surface and light guide may form a unitary, movable cover which can cover the surface of the LCD module either completely or partly. The control unit of the liquid crystal display is programmed so as to generate a picture on a sub-display always the right side up when viewed from the viewing direction. In practice this means that a picture generated for the viewing direction of a first sub-display is converted, by software, into a mirror image when viewed from the viewing direction of a second sub-display.
