Manufacturing method of plasma display panel and plasma display panel

摘要

The object of the present invention is to provide a high-intensity, reliable plasma display panel even when the cell structure is fine by resolving the problems such as a low visible light transmittance and low voltage endurance of a dielectric glass layer. The object is realized by forming the dielectric glass layer in the manner given below. A glass paste including a glass powder is applied on the front glass substrate (11) or the back glass substrate (21), according to a screen printing method, a die coating method, a spray coating method, a spin coating method, or a blade coating method, on each of which electrodes have been formed, and the glass powder in the applied glass paste is fired. The average particle diameter of the glass powder is 0.1 to 1.5 mu m and the maximum particle diameter is equal to or smaller than three times the average particle diameter. Furthermore, 5-30wt% of TiO2 is added to the glass powder in case the glass powder is included by a glass paste which is applied on the back glass substrate (21). By adding the TiO2, the dielectric glass layer (23) on the back glass substrate (21) reflects the light emitted from a phosphor (25) toward the front panel (10). <IMAGE>
