Abstract

The LCD (Liquid Crystal Display) (100) may be looked at (A,B) from either side. It has a central transparent liquid crystal module (10) with a transparent plate (12,14) on either side. The two transparent plates are illuminated from one edge by a single lamp (16) with a reflector system (18), each plate has a set of sawtooth notches (122,142) in the outer surface which reflect light inward onto the LCD. Most of the outer surface is flat, enabling the LCD to be viewed.
