Patent number: 7755733Abstract: A liquid crystal display apparatus includes a first display substrate, a second display substrate and a liquid crystal layer disposed therebetween. The first and second display substrates include first and second vertical inorganic alignment layers, respectively, to vertically align liquid crystal molecules of the liquid crystal layer. The first and second vertical inorganic alignment layers each include a silicon carbide and are formed on the first and second display substrates, respectively, by a chemical vapor deposition method or a sputtering method. Thus, processes for the vertical inorganic alignment layer may be simplified, thereby improving manufacturing productivity of the liquid crystal display apparatus.Type: GrantFiled: June 14, 2006Date of Patent: July 13, 2010Assignees: Samsung Electronics Co., Ltd., Industry-Academic Cooperation Foundation, Yonsai UniversityInventors: Soon-Joon Rho, Hong-Koo Baik, Kyung-Chan Kim, Jong-Bok Kim, Byoung-Har Hwang, Han-Jin Ahn

Publication number: 20100053513Abstract: In a method of manufacturing a display substrate, a color filter is formed on a first substrate including a switching element. A pixel electrode is formed on the first substrate including the color filter. An inorganic alignment layer including an inorganic compound is formed on the first substrate including the pixel electrode. Thus, impurities generated from the color filter may be blocked from flowing into a liquid crystal layer, and liquid crystal molecules of the liquid crystal layer may be aligned by the inorganic layer.Type: ApplicationFiled: July 1, 2009Publication date: March 4, 2010Inventors: Soon-Joon Rho, Baek-Kyun Jeon, Hee-Keun Lee, Hong-Koo Baik, Youn-Sang Kim, Jong-Bok Kim, Byoung-Har Hwang, Chu-Ji Choi, Min-Jung Lee

Publication number: 20070279562Abstract: An alignment layer for an LCD includes a thin layer of silicon oxide SiOx. The silicon oxide layer horizontally aligns liquid crystals thereon when the value of x is in the range from about 1.0 to about 1.5, but vertically aligns the liquid crystals when the value of x is in a range from about 1.5 to about 2.0. The alignment layer is readily formed on a large area of the substrate through chemical vapor deposition or evaporation deposition. Because the alignment layer is thermally and physically stable, the operational characteristics of the liquid crystal display employing this alignment layer are improved. In addition, the alignment layer has a thickness of about 500 to about 3000 angstroms thereby improving light transmittance of the LCD having the alignment layer.Type: ApplicationFiled: April 12, 2007Publication date: December 6, 2007Inventors: Soon-Joon Rho, Baek-Kyun Jeon, Kyoong-Ok Park, Hee-Keun Lee, Hong-Koo Baik, Kyung-Chan Kim, Jong-Bok Kim, Byoung-Har Hwang, Dong-Choon Hyun, Han-Jin Ahn
