DISPENSING APPARATUS FOR MANUFACTURING OF PLASMA DISPLAY PANEL

摘要

A dispensing apparatus for manufacturing a plasma display panel is provided to improve the picture quality of the plasma display panel by preventing color mixture of phosphor paste. A nozzle(501) is used for discharging phosphor paste in order to dispense the phosphor paste into a discharge space defined by a barrier rib. An adhesion prevention layer(502) having a low wetting property to the phosphor paste is formed on a peripheral part of an outline of the nozzle. The adhesion prevention layer is formed with a hydrophilic layer. The adhesion prevention layer is formed with a SiO2 layer. The adhesion prevention layer is formed by using a dipping method or an air spray method or a sputtering method.
