There is provided an efficient semi-transparent reflector (transflector) which reflects direct light under normal, ambient light conditions but permits back lighting of a display, such as an LCD display, under dark ambient light conditions. Such a "transflector" is inexpensive to manufacture and provides an efficient device in which the pattern and body color of the reflector can easily be changed.
