In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glass 14 is broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.

A plasma display panel is disclosed, which prevents luminance from being reduced, prevents error discharge from occurring due to crosstalk, and improves exhaust ability. Auxiliary barriers or projections are formed in a boundary portion between respective cells in a stripe type barrier structure. Alternatively, a predetermined groove is formed in a predetermined position of a dielectric layer in a lattice shaped barrier structure. In addition to these barriers, second barriers are formed at a greater width or at constant intervals. Thus, exhaust ability can be improved, and error discharge due to crosstalk can be prevented from occurring. Also, luminance in corner portions of the cell can be improved, and contrast can be improved even if a black matrix is not formed.
