ABSTRACT:
A photoelectron mask for photo cathode image projection includes a transparent substrate, and a pattern formed on a main surface of the transparent substrate. The pattern includes a non-transparent material. The mask also includes a photoelectron emission film formed so as to cover the main surface of the transparent substrate on which the pattern is formed. The photoelectron emission film includes a material selected from the group consisting of pure platinum, a platinum-rich material containing platinum as the major component, and a platinum compound.
