Definitions
- FIG. 6 is a plan view showing a configuration of a discharge cell portion of a conventional PDP.
- the display electrode 6 has the scan electrode 4 and the sustain electrode 5 arranged with a discharge gap 14 interposed therebetween, and a region surrounded by the display electrode 6 and the partition 12 is a luminescent pixel region 15. Then, the area of the adjacent gap 16 between the adjacent display electrodes 6 becomes the non-emission pixel area.
- FIG. 4 is a schematic configuration diagram for explaining the state of discharge of a conventional plasma display device.
- FIG. 6 is a plan view showing a configuration of a discharge cell portion of the plasma display device.
- FIG. 1 shows an example of a panel structure of a PDP used in a plasma display device according to an embodiment of the present invention.
- the PDP includes a front panel 21 and a rear panel 22. Have been.
- FIGS. 2 and 3 show one discharge cell portion of the front plate 21 in an enlarged manner.
- the dielectric layer 27 covers the display electrode 26, and covers the lower dielectric layer 27a formed on the substrate 23 on the front side.
- the lower dielectric layer 27a and the upper dielectric layer 27b having different softening points are formed on the discharge space side.
- a concave portion 27c is formed on the surface of the dielectric layer 27b of the dielectric layer 27 for each discharge cell.
- the concave portion 27c may be formed by hollowing out only the upper dielectric layer 27b for each discharge cell, and may be formed such that the bottom surface of the concave portion 27c becomes the lower dielectric layer 27a. .
- the softening point of the upper dielectric layer 27 b is lower than the softening point of the lower dielectric layer 27 a, and the softening point of the protective film 28 after the upper dielectric layer 27 b is formed. It is preferable that the temperature be higher than the temperature or the temperature during sealing or exhaust baking. This is to prevent the formed upper dielectric layer 27 from being softened again by a subsequent thermal process.
- the softening point of the upper dielectric layer 7b is 400 or more.
- the temperature difference of the softening point between the upper dielectric layer 27b and the lower dielectric layer 27a can be increased, which is advantageous for obtaining the effects of the present invention.
- the softening point of the upper dielectric layer 27b is set to 500 from 400 and the softening point of the lower dielectric layer 27a is set to 500: from 600 t to 600 :.
- a softening point of 40 0 from 5 0 0 t The components of the glass powder, increasing the composition ratio of P b 0, or, can be manufactured by lowering the composition ratio of S i 0 2, for example, whole as 1 0 0 wt%, lead oxide (P b O) 5 5% to 8 5% by weight, oxide boric element (B 2 0 3) 1 0 wt% to 3 0% by weight, silicon oxide (S i 0 2) 1% to 2 0 wt%, calcium oxide (C aO-) 1% to 1 0% by weight of aluminum oxide (A 1 2 ⁇ 3), etc. 0% to 3 wt% is found mentioned as additives .
- FIG. 4 is a schematic configuration diagram for explaining the state of discharge of the conventional plasma display device.
- the capacitance is constant on the surface of the dielectric layer, and discharge occurs near the electrode as shown in B. spread. This causes the phosphor to emit light in the area where light is blocked from transmitting to the front side, resulting in reduced efficiency.
- a problem that discharge easily occurs may occur.
- the dielectric layer 27 is formed into two lower dielectrics 27 a and an upper dielectric 27 b, and the lower dielectric 27 b is formed.
- the dielectric film thickness on the metal row electrode is increased to mask the metal row electrode.
- a method of suppressing light emission at a certain portion In the above-described conventional structure, light emission in the direction perpendicular to the electrode is suppressed, but discharge in the direction parallel to the electrode is not suppressed, and the discharge spreads to the vicinity of the partition. In this case, the efficiency may be reduced because the electron temperature is lowered by the partition walls.
- the partition is negatively charged. This attracts positive ions, and is known to be etched by being subjected to ion bombardment. As a result, the etched partition walls may be deposited on the phosphor, and the characteristics may be degraded.
