- FIG. 7B is the case of the PDP according to the prior art.
- the discharge sustaining voltage increased as the aging time increased, and after 2000 hours of aging, the final cell lighting voltage increased by about 30V. This is because ultraviolet rays generated by the discharge of the PDP are incident on the sealing material for a long time, the resin material contained in the sealing material is decomposed, and CH-based impurity gas is released inside the PDP. It is considered that the moss had a reduced purity.
- the voltage increase was 10 V or less even after aging for 2000 hours. This is because the ultraviolet rays generated by the discharge of the PDP are absorbed by the ultraviolet shielding walls, thereby preventing the release of impurity gas from the sealing material and suppressing the decrease in the purity of the discharge gas. It is done.
- the PDP according to the present embodiment is configured to have a getter formed continuously or intermittently along the inner periphery of the sealing material. According to this configuration, since the impurity gas released from the sealing material and the impurity gas that permeates through the sealing material can be adsorbed by the getter, the purity of the discharge gas sealed between the pair of substrates is low. It becomes possible to suppress the bottom. Therefore, an increase in the discharge voltage can be suppressed. Further, since the impurity gas can be adsorbed by the getter, it is possible to prevent the impurity gas from being adsorbed by the hygroscopic protective film.
- a getter that does not retain the impurity gas separated from the protective film by performing voltage marking (initial aging process) for a predetermined time between the substrates. Can be adsorbed. As a result, it is possible to complete the detachment of the impurity gas quickly, and the initial aging processing time can be shortened.
- the PDP according to the present embodiment has an ultraviolet shielding wall formed continuously along the inner periphery of the sealing material. According to this configuration, since the ultraviolet rays generated inside the sealing panel are absorbed by the ultraviolet shielding wall, it can be prevented from entering the sealing material.
