摘要

PROBLEM TO BE SOLVED: To prevent deletion of ribs and improve a brightness value of a plasma display panel (PDP). SOLUTION: In a back plate 31 having a board 2, a plurality of ribs 3 formed on a surface of the board 2 and a fluorescent layer 6 laminated on an inner wall face 5 of a display cell 4 consisting the space between two adjacent ribs 3, a tip end part 3a of the rib 3 is formed on a convex curved surface 3b. Also in the back plate 31, the fluorescent layer 6 is laminated on the convex curved surface 3b so that the thickness of the fluorescent layer 6 is gradually decreased toward a peak part 3d.
