Patent number: 7821206Abstract: The present invention relates to plasma display panel and manufacturing method thereof to simplify the manufacturing steps and reduce cost of production. In the present invention, a black layer formed between a transparent electrode and a bus electrode is formed together with a black matrix at the same time. In this case, the black layer is formed together with the black matrix in one. Cheap nonconductive oxide is used as a black powder of a black layer. Specifically, in case the black layer and the black matrix are formed in one, the bus electrode is shifted to a non-discharge area to improve the brightness of the plasma display panel.Type: GrantFiled: May 24, 2006Date of Patent: October 26, 2010Assignee: LG Electronics Inc.Inventors: Young Dae Joo, Tae Wan Choi, Seung Tea Park, Soon Hak Kim, Seok Dong Kang, Sang Tae Kim, Hyoung Kyun Bae
