<p>A method of manufacturing a plasma display panel including a sealing step of arranging front plate (22) formed with a display electrode, a dielectric layer, and a protective layer on a transparent substrate and rear plate (23) formed with an address electrode, a barrier rib, and a phosphor layer so as to face each other and sealing a periphery of front plate (22) and rear plate (23) with sealing material (33), where the sealing step includes a sealing material application step of applying sealing material (33) to rear plate (23), a tentative firing step of tentatively firing applied sealing material (33), and a sealing step of arranging front plate (22) and rear plate (23) so as to face each other and sealing the plates by softening and melting sealing material (33), and sealing material (33) is configured by a glass frit having bismuth oxide, with properties in that the softening point temperature changes with respect to the heating temperature and rate of change of the softening point temperature differs with respect to the heating temperature, as the main component, and the tentative firing temperature of the tentative firing step is set to a temperature lower by 10°C through 60°C from the temperature at which the rate of change changes.</p> |
