ABSTRACT:
A black matrix structure suitable for use in an active matrix liquid crystal display is described. The novel antireflective black matrix comprises successive layers of zinc oxide, molybdenum, a second layer of zinc oxide and a molybdenum mirror, all of which are deposited upon the front surface of a glass substrate member. An alternative structure includes the same sequence of layering on the back surface of the molybdenum mirror. The described black matrixes reduce reflectance of incident light to less than 0.5%. A technique for the preparation of the described structure involving cathodic sputtering is also described.
