Abstract

A reflector for use in liquid crystal displays is disclosed comprising a plate having a micro-lenticular surface over which are successive layers of reflective material, such as aluminum or silver and a light transparent material having a low index of refraction, i.e., an inex of refraction below that of SiO.sub.2, which is in optical contact with the reflective layer. The present invention also contemplates the method of fabricating such a reflective surface.
