Abstract
The present invention aims to provide a method of producing a plasma display panel in which the fluorescent substance layer or the reflection layer is formed easily and accurately even for a minute cell structure, and in which the fluorescent substance layer or the reflection layer is formed evenly in the channels between the partition walls formed in stripes, or such a layer is formed also on the sides of the partition walls. To achieve this purpose, a fluorescent substance layer or a reflection layer is formed by applying a fluorescent substance ink or a reflection material ink continuously onto the channels, the ink being spouted out from a nozzle which runs along the partition walls. The nozzle may be directed to one side of the plurality of partition walls while running. Pressure may be put upon the ink having been applied onto the channels so that the ink sticks to both sides of the partition walls. The ink may be continuously spouted out from a nozzle while a bridge is formed between the nozzle and both sides of the partition walls by surface tension of the ink. A plate with a plurality of partition walls and channels in between may be formed so that adsorption of the sides …
