Embodiment 1
[0108] Ne-4% Xe is used as the discharge gas, and it is introduced into the light-emitting area 15 under a pressure of 400 Torr, and the sealed plasma display panel 10 of the present invention is placed in a constant temperature and humidity chamber at 85°C and a humidity of 95%, and Measure the drop change in discharge voltage. exist Figure 6 (a) shows the relationship between the standing time and the discharge voltage.
[0109] For comparison, under the same conditions, the existing plasma display panel 110 ( Figure 11 ) discharge voltage. exist Figure 6 (b) shows the relationship between the standing time and the discharge voltage.
[0110] The final cell lighting voltage is the driving voltage required to start discharging all cells.
[0111] In addition, the first cell light-off voltage is the voltage for the first cell light-off when the driving voltage is gradually decreased from the state where all the cells are turned on.
[0112] In the plasma display panel ...
Embodiment 2
[0116] Next, the plasma display panel 10 of the present invention was placed in a constant temperature and humidity chamber at 50° C. and a humidity of 50%, and placed in a state where a voltage was applied to the electrodes to emit light, and the discharge voltage was measured. Figure 7 (a) shows the relationship between the time for applying a voltage to the electrode (aging time) and the discharge voltage.
[0117] For comparison, under the same conditions, the existing plasma display panel 110 ( Figure 11 ) discharge voltage. Figure 7 (b) shows the relationship between aging time and discharge voltage.
[0118] In the plasma display panel 10 of the present invention, even if the aging time reaches 2000 hours, the voltage rise is 10 V or less. This is because the ultraviolet rays emitted by the plasma are blocked by the sealing portion 17 and do not irradiate the sealing portion 41 , the sealing portion 41 is not decomposed, and the release of impurity gas is prevented....
