Abstract

PURPOSE: To prevent the irregular reflection of light from the fluorescent film and the reflection of external light, by forming mechanical coarse surface on the surface of the face plate and coating fine particles of silica on this surface with the binder.
CONSTITUTION: The fluorescent film 2 is formed at the inner surface of the face plate 1, and on the external surface (surface), as mechanical treatment, for example, by using sand-blast, the coarse surface 1a having the unevenness of several μm to several tens of μm is formed. Further, the extreme unevenness due to mechanical treatment is removed from the coarse surface 1a, for example, by coating fine particles 6 of silica of several to several tens of μm with the binder 7 such as polyulethane resin, and strong reflection preventing film 5 is formed with baking treatment. Thus, the reflection preventing film stable mechanically and chemically can be obtained and the lowering in the resolution of the screen can be avoided.
