1 is a view showing an embodiment of a method of manufacturing a partition material of a plasma display panel according to the present invention,

2A to 2C are perspective views of a discharge cell structure of an embodiment of a plasma display panel according to the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly to a partition material of a plasma display panel.

With the advent of the multimedia era, display devices that can express more detailed, larger, and more natural colors are required. However, the current CRT (Cathode Ray Tube) has a limit to compose a large screen of 40 inches or more, and the LCD (Liquid Crystal Display), PDP (Plasma Display Panel), and projection TV (Television) are used for high definition video. It is developing rapidly to expand.

The plasma display panel has a lower panel provided with an address electrode, an upper panel provided with a pair of sustain electrodes, and discharge cells defined as partition walls, and phosphors are coated in the discharge cells. Here, each discharge cell is filled with an inert gas containing a small amount of xenon and a main discharge gas such as neon, helium or a mixed gas of neon and helium. When discharge occurs in the discharge space between the upper panel and the lower panel, the vacuum ultraviolet rays generated at this time are incident on the phosphor to generate visible light, and the screen is displayed by the visible light.

The above-described plasma display panel has a spotlight as a display device because of its thin and light structure.

Here, the lower panel is provided with a partition wall to form a plurality of discharge spaces, that is, discharge cells, the partition wall is formed in a stripe type (or well type, etc.). The partition wall is made of a material such as low melting glass and a filler, and is formed directly on the lower panel by a screen printing method, or by a photosensitive paste method, a sand blast method, an etching method, or the like.

However, the barrier material of the conventional plasma display panel described above has the following problems.

In the case of the photosensitive partition material, the refractive index of base glass is 1.5-1.7, It is characterized by the above-mentioned. Conventional photosensitive partition glass is composed of Al ₂ O ₃ -B ₂ O ₃ -SiO ₂ , and in order to have a firing temperature at 560 to 600 ° C., alkali oxides Na 2 O and Li 2 O are added to reduce thermal characteristics. And photosensitive partition glass powder is disperse | distributed to the photosensitive vehicle, and the photosensitive partition wall paste is manufactured. At this time, the vehicle should have the same refractive index as the glass powder. That is, to prevent light scattering to a dry film having a thickness of about 200 micrometers in the dry film state in the exposure step to increase the straightness of the light.

Therefore, in order for the vehicle for preparing the partition material to have a refractive index of 1.5 to 1.7, the molecular weight of the binder in the vehicle must be increased or a large number of functional groups are attached to the binder. At this time, there may be a problem that a large amount of residual coal may be generated in the calcining process of the partition wall and the selection range of the binder is narrowed. Xanthan lowers the color purity of the phosphor, decreases the reflectance of the partition wall, and decreases the luminance, and may also act as an impure gas in the discharge space.

In addition, since the firing temperature is about 560 to 600 ° C. due to the thermal characteristics of the glass itself in the photosensitive partition material, it is not applicable to a soda lime substrate. That is, to apply to a soda-lime substrate, the photosensitive partition material which can be baked at 520 degreeC is needed. In addition, there is a problem in that the range of the partition material is very narrow in order to satisfy the above-mentioned refractive index.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a partition material of a plasma display panel including glass having a refractive index of 1.5 or less or 1.7 or more.
