Abstract

A plasma display panel and a manufacture method thereof are disclosed. The plasma display panel having a plurality of discharge pixels, the panel includes a first barrier rib, with a first width, formed to function as a boundary between the discharge pixels, a second barrier rib, with a second width, formed to function as a boundary between the discharge pixels, wherein the second width is more than the first width, and a black matrix formed over the second barrier rib.

Claims (20)

1. A plasma display panel for displaying an image, the panel comprising:

a plurality of unit pixels comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel, wherein the first sub-pixel corresponds to a red color sub-pixel, the second sub-pixel corresponds to a green color sub-pixel, and the third sub-pixel corresponds to a blue color sub-pixel;

a first barrier rib formed to function as a boundary between the first, second and third sub-pixels and formed in a longitudinal direction of the first, second and third sub-pixels;

a second barrier rib formed to function as a boundary between the plurality of unit pixels and formed in a longitudinal direction of the first, second and third sub pixels, wherein the second barrier rib has a width that is more than a width of the first barrier rib;

a longitudinal black matrix formed over the second barrier rib; and

a lateral barrier rib comprising a channel and formed in a vertical direction of the first barrier rib and the second barrier rib.

2. The panel of claim 1 , wherein a width of the longitudinal black matrix is less than a width of the second barrier rib.

3. The panel of claim 1 , wherein a width of the second barrier rib equals 170 μm.

4. The panel of claim 1 , wherein a width of the longitudinal black matrix equals 90 μm.

5. The panel of claim 2 , wherein a difference between a width of the longitudinal black matrix and a width of the second barrier rib ranges from 10 μm to 200 μm.

6. The panel of claim 5 , wherein the difference ranges from 40 μm to 80 μm.

7. The panel of claim 1 , wherein the longitudinal black matrix is formed at a front substrate.

8. The panel of claim 1 , wherein a difference between a width of the first barrier rib and a width of the second barrier rib ranges from 30 μm to 300 μm.

9. The panel of claim 1 , wherein areas of the red color sub-pixel, the green color sub-pixel, and the blue color sub-pixel are different from one another.

10. The panel of claim 9 , wherein an area of the blue color sub-pixel is the largest.

11. The panel of claim 10 further comprising:

a lateral barrier rib of a width determined by the area of the sub-pixels.

12. The panel of claim 11 , wherein a channel is formed on the lateral barrier rib.

13. The panel of claim 12 , wherein a width of the channel remains constant for each of the sub-pixels.

14. The panel of claim 12 , wherein a width of the channel varies for each of the sub-pixels.
