ABSTRACT:
The present invention relates to a black paste composition and an upper plate of plasma display panel using the same. The upper plate of plasma display panel comprises an upper substrate, a transparent electrode disposed on a predetermined position of the upper substrate, a bus electrode disposed on a predetermined position of the transparent electrode and a black matrix disposed between the transparent electrode and the bus electrode, and in each discharge cell.The black paste composition comprises about 5 to 25 parts by weight of a heat resistant black pigment; about 5 to 20 parts by weight of a glass powder; about 25 to 30 parts by weight of a binder; about 5 to 15 parts by weight of a photopolymerization monomer; about 1 to 10 parts by weight of a photopolymerization initiator; and about 20 to 35 parts by weight of a solvent.In the black paste composition and the upper plate of the plasma display panel using the same according to the present invention, the contact resistance between the bus electrode and the transparent electrode is low, the black matrix has a high black rate, and the manufacturing cost is reduced since the black matrix is made of the black paste composition containing MnCo2O4.
