ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a PDP (Plasma Display Panel) and more particularly to a PDP for transforming discharge emission to visible rays with a phosphor and a method of producing the same.
A PDP has been proposed in various forms in the past. With the spread of PDPs, a demand for PDPs usable in various environments is increasing. Specifically, while the application of PDPs has heretofore been limited to public display, it is now extended to personal television receivers. The prerequisite with PDPs for personal television receivers is that PDPs sufficiently adapt to environments in which they are situated. However, the problem with the conventional PDPs is that they consume great power in achieving high emission efficiency and high luminance. In addition, the resulting heat radiation reduces the durability, i.e., service life of the PDPs.
Technologies relating to the present invention are disclosed in, e.g., Japanese Patent Laid-Open Publication Nos. 57-25651, 62-257862, 2-148559, 2-201860, 4-133004, 8-96751, and
9-231910.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a PDP having high luminance and long service life.
In accordance with the present invention, a PDP includes a pair of glass substrates respectively located at a scanning side and a data side and facing each other with the intermediary of a preselected gas discharge space. A phosphor layer is formed on at least one of the two glass substrates. A reflection layer is formed on the surface of the other glass substrate facing the one glass substrate for reflecting vacuum ultraviolet (UV) rays.
Also, in accordance with the present invention, a method of producing a PDP includes the steps of positioning a pair of glass substrates face to face while forming a preselected gas discharge space between the glass substrates, forming a phosphor layer on at least one of the glass substrates, and forming a reflection layer on the surface of the other glass substrate facing the one glass substrate for reflecting vacuum UV rays.
