Abstract

PURPOSE: To prevent the seeing of pins for fixing a shadow mask from a face surface, by forming a skirt portion of a glass panel by glass composition, which contains a coloring agent of metal or metallic oxides and has low photo-transmittivity characteristics.
CONSTITUTION: One portion or the whole of a skirt portion 2 of a glass panel 1 is made up by glass composition, which contains a coloring agent of not less than one kind of metal or metallic oxides and has low photo-transmittivity characteristics different from a face plate portion 50. The panel 1 is built up in such a manner that fused glass, to which the coloring agent is added, is first through into a portion 60 of an automatic molding instrument 61A, fused glass 21 for forming a face surface is charged and a plunger 63 is let fall. Thus, pins 5 for a shadow mask are lost to sight from the observation side because the rays of light incident are approximately absorbed by a colored glass portion, and the desirable effect from the viewpoint of a design can be obtained.
