Abstract:
1. A method of manufacturing a plasma display panel without any injection tip, comprising: providing a lower glass substrate, with an electrical discharge cell provided on an upper surface of the lower glass substrate to define a predetermined display pattern of the plasma display panel, a fluorescent material applied on a surface of the electrical discharge cell, and a first transparent electrode having a high conductivity and provided on a lower surface of the lower glass substrate; providing an injection hole on a predetermined portion of the lower glass substrate to exhaust air from and inject inert gas into the electrical discharge cell through the injection hole; attaching an upper glass substrate on the upper surface of the lower glass substrate using a sealing line, with a second transparent electrode having a high conductivity and provided on a lower surface of the upper glass substrate; injecting the inert gas into the electrical discharge cell of the lower glass substrate using a vacuum apparatus through the injection hole while the air is exhausted from the electrical discharge cell to an outside of the plasma display panel by the vacuum apparatus through the injection hole, thus creating a vacuum in the electrical discharge cell; placing a sealing material on a lower end of the injection hole to seal the injection hole; and hardening the sealing material placed on the lower end of the injection hole by exposing the sealing material to ultraviolet rays, thus maintaining the vacuum in the electrical discharge cell.
