Abstract
A plasma display panel operated at a high luminous efficiency even with a fine cell structure and its manufacturing method. An AC type PDPhas a phosphor filmcomprising a thinned crystal over the surface of a dielectric protecting filmin a front panelThe phosphor filmis a film formed by EB evaporation, the film thickness of which is set in a range where a sufficient luminous efficiency and a visible light penetration efficiency can be secured when the phosphor filmis irradiated with ultraviolet rays.
