Abstract
Provided is a PDP in which a weak discharge is always generated in a stable manner to lower the firing voltage, the generation of the reset luminous points is restricted to improve the image quality, and reduction of the luminous efficiency and reduction of the luminance are restricted to improve the luminance. A manufacturing method of the PDP is also provided. The PDP includes a front panel and a back panel arranged to face each other with a discharge space between the panels. A phosphor layer is provided in an area of the back panel that faces toward the discharge space. Part of the surface of the phosphor layer is covered with a phosphor-coating film as a high γ member. The phosphor-coating film is made of a material having a higher secondary electron emission coefficient than a material of the phosphor layer. The high γ member and the remaining are of the surface of the phosphor layer are exposed to the discharge space.
