ABSTRACT:
A non-specular reflecting surface for use in a Liquid Crystal Display is obtained by randomly embedding particles in a layer of a resin solution and then baking to hardness. The particles' sizes are approximately the same as the layer's thickness, so a randomly uneven surface is the result. The particles are most commonly, but not necessarily, commercially available plastic microspheres. If a photosensitive resin is selected, it may be shaped into a desired pattern without the need for a separate photoresist and etch step. When a high reflectance metal is deposited onto the resin surface it becomes an effective non-specular reflector.
