Patent number: 8018561Abstract: Electrode slit portions are formed in a pixel electrode in a direction of crossing a slit for dividing a liquid crystal layer into a plurality of domains. A titanium oxide film is formed so as to be exposed to the liquid crystal layer side via the electrode slit portions, the titanium oxide film having a relative dielectric constant higher than that of an organic film formed at positions corresponding to the electrode slit portions. By the titanium oxide film, an electric field of each domain is set, angles between the director in the vicinity of the electrode slit portion and transmission axes of polarizing plates are made to approximately 45°, and a decrease in transmittance caused by the falling direction of the director can be suppressed. The transmittance and contrast ratio are secured, and simultaneously an excellent wide viewing angle range can be obtained.Type: GrantFiled: January 6, 2009Date of Patent: September 13, 2011Assignee: Toshiba Matsushita Display Technology Co., Ltd.Inventors: Masaki Obi, Azusa Ikeda, Hideki Ito, Yasushi Kawata, Akio Murayama
