Abstract
A color pick-up tube face plate with shading films is disclosed. These shading films are stripe-shaded opaque films, and are formed between the transparent glass plate and the stripe-shaped color filters. As the boundary portions of all the filters are positioned on these shading films, the light incidented around the boundary portions is hindered by the shading films. For this reason, light reflection or scattering around the boundary portions is effectively eliminated, and a pure high quality color picture is obtained.
