Patent ID: 7767290

Claim:
A green sheet for barrier ribs of plasma display panel comprising: a base film; a first film-forming layer including about 100 parts by weight of a mixture comprising a glass powder and a filler, about 0.01 to 2 parts by weight of a dispersing agent, about 1 to 10parts by weight of a plasticizer, about 10 to 20 parts by weight of a binder, and disposed on a surface of the base film; and a second film-forming layer including about 100 parts by weight of a mixture comprising a glass powder and a filler, about 0.01 to 2 parts by weight of a dispersing agent, about 1 to 10parts by weight of a plasticizer, about 10 to 20 parts by weight of a binder, and disposed on a surface of the first-film forming layer, wherein the second film-forming layer has an etching rate different from an etching rate of the first film-forming layer, and the filler is at least one selected from the group consisting of Al 2 O 3 , ZnO, TiO 2 and mixtures thereof, wherein the green sheet is a sheet for transferring the first and second film-forming layers to a substrate of the plasma display panel, wherein a density difference between the first film-forming layer and the second-film forming layer is between about 0.01g/cm 3 and 1.0g/cm 3 .
