Patent number: 7453209Abstract: A plasma display panel includes a first substrate and a second substrate with discharge cells partitioned therebetween. First electrodes and second electrodes surround the discharge cells and are respectively disposed proximate to opposite ones of the first and second substrates. The first electrodes are connected to each other and the second electrodes are connected to each other in a first direction. Address electrodes are between and spaced apart from the first and second electrodes along the direction perpendicular to the planes of the first substrate and the second substrate, and are connected in a second direction crossing the first direction. The address electrodes also surround the discharge cells.Type: GrantFiled: April 19, 2006Date of Patent: November 18, 2008Assignee: Samsung SDI Co., Ltd.Inventors: Tae-Joung Kweon, Kyoung-Doo Kang

Patent number: 7453206Abstract: A PDP has first and second substrates which face each other with a space in between. A display electrode pair and a dielectric layer are formed on the first substrate, and a plurality of discharge cells are formed between the first and second substrates along the display electrode pair. In this construction, two or more depressions are provided in the dielectric layer in an area corresponding to each discharge cell. This improves luminous intensity and illumination efficiency. Also, to form the dielectric layer on the first substrate, first a transfer film is made by providing a dielectric precursor layer on a support film, then depressions are formed in the dielectric precursor layer of the transfer film, and lastly the dielectric precursor layer of the transfer film is transferred onto the first substrate. This decreases the number of manufacturing steps and increases the yield, thereby reducing manufacturing costs.Type: GrantFiled: May 27, 2002Date of Patent: November 18, 2008Assignee: Panasonic CorporationInventors: Morio Fujitani, Hiroyuki Yonehara, Masaki Aoki, Keisuke Sumida, Hideki Asida, Junichi Hibino
