Abstract: A PDP operates with high luminous efficiency and reproduces colors faithfully. When sealing the PDP, a sealant layer (15) is formed around the facing main surfaces of the front panel (10) and the back panel (20). Protrusions (16) and depressions (17) are formed in parts of the sealant layer (15) to produce gaps (18) at the periphery of the PDP. The heating performed to soften the sealant layer (15) is conducted in a dry gas atmosphere. As a result, moisture passes from the inner space of the PDP through the gaps (18) and out of the PDP, thereby reducing the heat deterioration in the blue phosphor layer (25).

Abstract: A plasma display panel comprising plural kinds of phosphor layers emitting different colors of fluorescent light, at least one kind of the phosphor layer being formed of a mixed phosphor obtained by mixing a phosphor having a surface potential with a negative polarity and a phosphor having a surface potential with a positive polarity. By using the mixed phosphor, the negative polarity of the surface potential is changed to the positive polarity, thereby reducing the discharge error and discharge variation, and improving the quality of display.
