ABSTRACT:
A novel light scattering reflector and methods of making and using it are disclosed. The reflector, which can advantageously be used in conjunction with liquid crystal displays, includes a layer carrier formed of glass or rigid PVC foil. The layer carrier is roughened by sandblasting, impressing with a grooved die, or by other techniques to provide an irregular surface. A reflective metal coating is subsequently evaporated onto the roughened surface to complete the reflector structure. Auxiliary materials may also be coated onto the layer carrier to improve the characteristics of the device.
