Plasma display panel

摘要

A plasma display panel is provided in which an operational quality is prevented from being deteriorated by resonance of a substrate. The plasma display panel includes a partition for dividing a discharge gas space defined by a pair of substrates and a sealing material 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. 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 audio frequency region of a human.
