Claim:
A plasma display panel comprising: a first and a second substrates opposed to each other and sealed at a peripheral portion of the opposed area with a sealing material so as to define a discharge gas space; a partition attached to the second substrate for dividing the discharge gas space in accordance with a cell arrangement of a display screen; a gap between the substrates, the size of the gap being dependent on the height of the partition that is apart from the sealing material; a plurality of electrodes arranged on both the first and the second substrates; and a void space between the upper surface of the partition and the opposed surface to be contacted at the vicinity of an end portion of the partition, the void space being generated when the end portion of the partition is raised, wherein a natural frequency of a portion of the first substrate from an inner edge of the void space to an inner edge of the sealing material is higher than 20.000 hertz.
