SOLUTION: The phosphor for the display device is the green light-emitting phosphor having a composition substantially represented by the general formula: ZnS:Cua, Alb (wherein, a and b denote each the amount within the range of 1×10
-5 ≤a≤1×10
-3 g and 1×10
-5 ≤b≤1×10
-3 g) based on 1 g of zinc sulfide which is a phosphor matrix and emitting light by excitation with electron beams. In the emission spectrum, the area at a shorter wavelength than the wavelength which is shorter than the peak wavelength by 60 nm is ≤1.6% based on the total area of the whole spectrum.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of luminance of an image forming device, by inexpensively and simply forming a phosphor screen with a metallic back whereby an electron emitting element and the phosphor screen are prevented from being destroyed and deteriorated by abnormal discharge. SOLUTION: The adhesive layer having a pattern corresponding to the pattern of a phosphor layer is formed on the metallic film of a transfer film and/or the phosphor layer. Only a metallic film part abutting on the adhesive is left behind when transferring the metallic part, and thereby the metallic film having the same pattern as that part is transferred and formed on the phosphor layer. The pattern of the phosphor layer containing the adhesive may be formed in a phosphor layer forming process.
