PHOTOELECTRON MASK AND PHOTO CATHODE IMAGE PROJECTION METHOD USING THE SAME

摘要

A photoelectron mask for photo cathode image projection includes a transparent substrate (11), a pattern (12) formed on a main surface of the transparent substrate. The pattern includes a non-transparent material. The mask also includes a photoelectron emission film (13) formed so as to cover the main surface of the transparent substrate on which the pattern are 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.
