Abstract
A plasma display panel has plurality discharge cells disposed between a pair of opposing first and second substrates. Each of the discharge cells includes at least: at least one pair of electrodes for generating a discharge for display; a discharge gas; and a phosphor film for emitting visible light by being excited by ultraviolet light produced by the discharge of the discharge gas. Laminated members are dispersed in a plane within each of the discharge cells inside the first substrate from which visible light for display is emitted. Each of the laminated members includes a light absorption layer disposed on a side of the first substrate on which ambient light is incident and a light reflection layer disposed on a phosphor-film side of each of the laminated members.
