Abstract: The present invention relates to a plasma display panel, more particularly, to a plasma display panel apparatus and manufacturing method of the same, which is capable of minimizing a gap between a seal layer and a UV Ultra Violet ray/silicon desiccant layer due to an air bubble, when the front panel and the rear panel of the plasma display panel are in the sealing process. A plasma display panel according to the present invention comprises a front substrate; a rear substrate; a seal layer which is formed between the front panel and the rear panel; and a desiccant layer which is in contact with the front panel, the rear panel and the seal layer.

Abstract: The method for preparing an artificial marble having a crack pattern is disclosed. The method includes preparing a first and a second polymeric compositions of different viscosities; pouring the first polymeric composition into a molding cell; pouring the second polymeric composition onto the first polymeric composition; allowing migration of the first polymeric composition to the upper part of the second polymeric composition due to the difference in viscosity between the first and the second compositions; and curing the two polymeric compositions to form a crack pattern. The viscosity of the first polymeric composition is lower than that of the second polymeric composition.
