Patent number: 7245337Abstract: A reflection electrode has an undulated shape and whose normal direction is distributed unevenly to a specific azimuth angle and whose reflection light intensity depends on said azimuth angle. Openings are formed in that area of the reflection electrode which has a tilt angle of 0 degree to 2 degrees and/or a tilt angle of 10 degrees or higher. The retardation of a liquid crystal layer is changed by making the liquid crystal molecular alignment mode different between the openings and the reflection electrode, so that the intensity of output light is increased in reflection mode as well as in transmission mode. The balance of colors displayed in transmission mode is determined by determining the area of the openings in pixels of each color, and the color temperature is set higher in transmission mode than in reflection mode. This provides a semi-transmission type liquid crystal display which has an excellent visibility in reflection mode as well as in transmission mode.Type: GrantFiled: October 17, 2005Date of Patent: July 17, 2007Assignee: NEC LCD Technologies, Ltd.Inventors: Hidenori Ikeno, Masayoshi Suzuki, Youichi Murayama, Michiaki Sakamoto, Fumihiko Matsuno, Hironori Kikkawa, Yuichi Yamaguchi

Patent number: 7015995Abstract: An anisotropic reflection electrode has an undulated shape and whose normal direction is distributed unevenly to a specific azimuth angle and whose reflection light intensity depends on said azimuth angle. Openings are formed in that area of the reflection electrode which has a tilt angle of 0 degree to 2 degrees and/or a tilt angle of 10 degrees or higher. In one aspect, the retardation of a liquid crystal layer is changed by making the liquid crystal molecular alignment mode different between the openings and the reflection electrode, so that the intensity of output light is increased in reflection mode as well as in transmission mode. The balance of colors displayed in transmission mode is determined by determining the area of the openings in pixels of each color, and the color temperature is set higher in transmission mode than in reflection mode. This provides a semi-transmission type liquid crystal display which has an excellent visibility in reflection mode as well as in transmission mode.Type: GrantFiled: August 7, 2002Date of Patent: March 21, 2006Assignee: NEC LCD Technologies, Ltd.Inventors: Hidenori Ikeno, Masayoshi Suzuki, Youichi Murayama, Michiaki Sakamoto, Fumihiko Matsuno, Hironori Kikkawa, Yuichi Yamaguchi

Patent number: 5409782Abstract: The present invention relates to a composite film. More particularly, the present invention relates to a composite compound film and composite compound multilayered film, comprising a metal, an alloy and/or an inorganic substance with an organic substance, which is excellent in decorative properties, protection and functionality. Methods applicable for forming such a composite compound film include the technique of evaporating a metal, an alloy, and/or an inorganic substance and an organic substance, simultaneously exciting the evaporated particles, and causing vapor-deposition in the state of ionized particles, neutral particles or radicals, and a method of sputtering, without excitation, etc.Type: GrantFiled: November 22, 1993Date of Patent: April 25, 1995Assignee: Orient Watch CompanyInventor: Youichi Murayama
