Problems solved by technology

However, since the prior art pre-filter is composed of multiple layers, there is a problem because the pre-filter has a predetermined or higher thickness
More specifically, it is difficult to form the optical property improving film included in the front filter using only the optical property improving material
Therefore, there are problems of long processing time and high manufacturing cost

Abstract

The present invention relates to plasma display panels, and more particularly, to the structure of plasma display panels. The plasma display panel according to the present invention has an optical characteristic improving material included in any one of the upper dielectric layer, the protective film and the upper substrate. As a result, according to the present invention, the light characteristic improving film can be omitted from the front filter, the plasma display panel can be made thin and the manufacturing cost can be saved.

Description

technical field [0001] The present invention relates to plasma display panels, and more particularly, to the structure of plasma display panels. Background technique [0002] Generally, in a plasma display panel, barrier ribs formed between an upper panel and a lower panel form a unit cell. Each cell is filled with a mixed gas consisting of a main discharge gas, such as neon (Ne), helium (He), or Ne+He, and a small amount of xenon (Xe). If an inert gas is discharged with a high-frequency voltage, it generates vacuum ultraviolet rays. The fluorescent material formed between the barrier ribs is excited to realize an image. [0003] More specifically, the three-electrode AC surface discharge type plasma display panel has advantages of low voltage driving and long product lifespan because wall charges are accumulated on the surface under discharge and electrodes are protected from splashes generated by the discharge. [0004] figure 1 The structure of the plasma display pane...
