Publication number: 20080259002Abstract: The present invention relates to a plasma display apparatus. The plasma display apparatus includes an upper substrate; first and second electrodes formed on the upper substrate; a lower substrate disposed opposite to the upper substrate; and a third electrode formed on the lower substrate. At least one of the first and second electrodes is formed as one layer, and includes first and second electrode lines formed in a direction intersecting the third electrode and a connecting electrode that connects the first and second electrode lines. The distance between the first and second electrode lines has a value of 2 or more in one discharge cell. Accordingly, manufacturing cost of a plasma display panel can be saved by removing a transparent electrode made from ITO. Further, a discharge firing voltage can be reduced and the luminance of a display image can also be improved by variably adjusting the distance between two electrode lines constituting a scan or sustain electrode.Type: ApplicationFiled: April 17, 2008Publication date: October 23, 2008Applicant: LG Electronics Inc.Inventors: Jeong Hyun HAHM, Seong Nam RYU, Woo Tae KIM, Young Gwang KANG, Jin Yeop KIM, Hee Kwon KIM
