Abstract
A plasma display panel comprises a transparent front panel plate including a display electrode and a protective layer covering at least the display electrode, a back panel plate, a discharge space formed by adhering the transparent front panel plate and the back panel plate to each other, and a phosphor layer formed to be exposed to the inside of the discharge space. The protective layer is made of a first metal oxide layer formed to cover the display electrode, and a second metal oxide layer formed to cover the first metal oxide layer. The linear thermal expansion coefficient of the second metal oxide layer is larger than that of the first metal oxide layer.
