PROBLEM TO BE SOLVED: To provide a PDP having a phosphor layer with higher luminance by forming a phosphor layer using a phosphor of a specific composition in manufacturing a plasma display panel(PDP). SOLUTION: Display electrodes X, Y which are the electrodes for plane discharge are provided inside a glass substrate 11 in the front side and coated with a dielectric layer 17 in relation to a discharge space 30. A protection film 18 which is composed of MgO of large secondary electron emission coefficient and has the thickness of several thousands A is provided on the surface of the dielectric layer 17. Because the display electrodes X, Y are arranged in the front side of the discharge space 30, a plane discharge is set to the wide range and the shield of the display light is set to the minimum so that they are constituted of a broad-width transparent conductive film 41 composed of Nesa film, etc., and a narrow metal film 42 for compensating its conductivity. Paste for forming a phosphor layer is an aggregate of phosphor particles formed by mixing the primary particles and the secondary particles, and the phosphor particles having such particle size distribution that 50% grain size and the primary particle size are substantially coincided with each other are used. |
