ABSTRACT:
A cathode-ray tube has a faceplate on which is formed an anti-reflective coating with at least two layers. The first layer is formed on the outer surface of the faceplate by spin-coating an alcohol solution of an organometallic compound, leaving a porous metal oxide layer. The second layer is formed on the first layer by spin-coating an alcohol solution of silicon alkoxide, leaving a porous silica layer. Both layers are baked, and the first layer is baked or cured before the second layer is applied. The first layer has a higher index of refraction than the second layer.
