A partition is formed by the process including a step for providing a sheet-like partition material that covers a display area and outside thereof on the surface of the substrate, a step for providing a mask for patterning that covers the display area and the outside thereof, so that a pattern of the portion arranged outside of the display area of the mask is a grid-like pattern, a step for patterning the partition material covered partially with the mask by a sandblasting process, and a step for baking the partition material after the patterning.

Method for forming partitions of plasma display panel by using sandblasting process

In accordance with the present invention, there is provided a method of manufacturing a plasma display panel of the type which includes a discharge space defined between a pair of substrates and sealed by a sealant, the method comprising a first step of forming the sealant on at least one of the substrates and stacking one substrate on the other through the intermediation of the sealant, a second step of reducing the pressure in the space existing between the pair of substrates due to the presence of the sealant and melting the sealant by heating, a third step of curing the sealant to thereby firmly attach the pair of substrates to each other and define a predetermined discharge space, a fourth step of removing impurities in the discharge space, and a fifth step of filling the discharge space with discharge gas.

Manufacturing method of plasma display panels

A plasma display panel of a matrix display type, having a first electrode and a second electrode which constitute a main electrode pair, the first electrode and the second electrode being covered with an insulating layer against a discharge gas, wherein the insulating layer comprises a magnesium oxide film formed at least as a surface layer thereof which is in contact with the discharge gas, the magnesium oxide film having an impedance in the range of 230 to 330 k&OHgr;/cm,at a frequency of 100 Hz.
