Disclosed is a plasma display panel comprising a transparent front panel plate (21) comprising a display electrode (22) and a metal oxide layer (27) covering at least the display electrode (22), a back panel plate (28), a discharge space formed by adhering the transparent front panel plate (21) and the back panel plate (28) to each other, and a phosphor layer (32) formed to be exposed to the inside of the discharge space. The metal oxide layer (27) is made of a first metal oxide layer (27-1) formed to cover the display electrode (22), and a second metal oxide layer (27-2) formed to cover the first metal oxide layer (27-1), and the linear thermal expansion coefficient of the second metal oxide layer (27-2) is larger than that of the first metal oxide layer (27-1). Using this metal oxide layer (27) having the bi-layered structure as a protective layer for the display electrode (22), a plasma display panel capable of displaying highly minute images can be produced at low costs. |
