A plasma display panel is provided in which operational quality is prevented from being deteriorated by resonance of a substrate. The plasma display panel includes a partition (29) for dividing a discharge gas space defined by a pair of substrates (11, 21) and a sealing material (35) in accordance with a cell arrangement of a display screen. There is a void space between the upper surface of the end portion of the partition and the surface of the opposed substrate, the surfaces contacting each other at the outer edge (295) of the partition. The natural frequency of the portion from the inner edge of the void space to the inner edge of the sealing material is raised above the range of human hearing by careful choosing of the length of the portion (L) and the density, thickness and Young's modulus of the substrate material <IMAGE> |
