This prevents problems that occur in the manufacturing process of PDP4 ( Figure 12 described later).
- the glass substrate 104C is bonded to the resin substrate 102C with an adhesive or the like. Note that the glass substrate 104C may be adhered to the resin substrate 102C by being fitted into the recess 120 and then subjected to frictional force and adsorption force with the inner surface of the recess 120 without using an adhesive.

- the address electrode 206 is formed (electrode formation step).
- step S216 an ink containing phosphor fine particles (nanoparticles) is sequentially applied to the side wall of the rib 210 so as to cover the address electrode 206 by an inkjet method, and organic substances such as a solvent are removed at 150 to 200 degrees.
- phosphor layers 212R, 212G, and 212B (FIG. 1) are formed (phosphor formation step).
- the step of forming the dielectric layer 208 performed before the formation of the phosphor layers 212R, 212G, and 212B in the first embodiment can be omitted. This is because the address electrode 206 is formed after the rib 210 is formed, and therefore it is not necessary to protect the address electrode 206 when the rib 210 is formed.
- the SiO layer is formed by sputtering as in step S206 described above (the processing temperature is
- step S2108 the substrates 100C, the 200C force protection layer 110, and the ribs 210 are bonded together so as to contact each other. Then, as shown in FIG. 11, the periphery of the front substrate 100C and the rear substrate 200C is bonded using the resin seal members 230 and 232 (the processing temperature is room temperature).
- step S220 the gas force through holes 222 and 224 in the discharge space DS are exhausted (vacuum exhaust).
- the protective layer (MgO) is formed in an inert gas atmosphere, it is possible to prevent moisture from adsorbing to MgO.
- evacuation can be performed at a relatively low temperature of about 150 to 200 degrees, for example.
- Ne— A discharge gas such as Xe gas is enclosed.
- PDP4 force S is completed.
- the processing temperature of each processing process for manufacturing PDP4 can be made lower than the heat resistance temperature of the resin substrates 102C and 104C. Therefore, it is possible to prevent the resin substrates 102C and 104C from being deformed or denatured during the manufacturing process.
- the PDP 4 can be manufactured in a state where the glass substrates 104C and 204C are fitted in the recesses 120 and 220 of the resin substrates 102C and 202C. For this reason, the glass substrates 104C and 204C can be protected by the resin substrates 102C and 202C during the manufacture of the PDP4. As a result, the glass substrates 104C and 204C can be easily handled in the manufacturing process.
- FIG. 13 shows a method for manufacturing the plasma display panel PDP5 in the fifth embodiment.
- the same processing in the fourth embodiment is given the same step number, and detailed description thereof will be omitted.
- the plasma display panel PDP4 of the fourth embodiment is manufactured.
- the plasma display panel of this embodiment does not have the through holes 222 and 224 shown in FIG. 9 described above.
- the processing power of steps S208 and S218 is performed in an atmosphere of Ne—Xe gas (discharge gas). For this reason, when the front substrate 100C and the rear substrate 200C are sealed, Ne—Xe gas is enclosed in the discharge space DS. As a result, step S220 (discharge gas sealing step) of the fourth embodiment is not necessary.
- Other manufacturing methods are the same as those in FIG.
- the discharge gas sealing step can be eliminated.
- the through holes 222 and 224 shown in FIG. 9 described above need not be formed in the back glass substrate 204C and the resin substrate 202C. As a result, the manufacturing process can be simplified.
- the filter 112 is attached to the surface of the resin substrate 102 .
- the invention is not limited to the powerful embodiments.
- the surfaces of the front glass substrates 104 and 104C are covered with the resin substrates 102 and 102C. Since the shock applied to the plasma display panel from the opening 302 side (image display surface side) can be absorbed by the resin substrates 102 and 102C, protective glass can be eliminated. As a result, plasma display panels and plasma devices It is possible to reduce the parts cost of the play device.
- the example in which the resin substrates 102C and 202C are attached to the front glass substrate 104C and the rear glass substrate 204C has been described.
- the invention is not limited to the powerful embodiments.
- a resin substrate may be attached to either the front glass substrate or the rear glass substrate. In this case as well, the weight of the plasma display panel can be reduced without reducing the strength.
- the present invention can be applied to a plasma display panel and a plasma display device.
