Patent number: 9454939Abstract: A display apparatus is configured to allow a user positioned in a first direction to visually recognize a first image and to allow a user positioned in a second direction different from the first direction to visually recognize a second image. The display apparatus includes a display unit that alternately displays the first and second images; an irradiation unit that provides irradiation light; a color filter that respectively includes first and second areas for the first and second images, through which the irradiation light is transmitted; and a distribution unit that distributes the irradiation light transmitted through the first area of the color filter to the first direction and through the second area of the color filter to the second direction. The color filter includes color components of three primary colors and a white color.Type: GrantFiled: September 9, 2015Date of Patent: September 27, 2016Assignee: Japan Display Inc.Inventors: Tae Nakahara, Chihiro Tanaka

Patent number: 8953134Abstract: A liquid crystal display panel is provided and includes a pair of substrates facing each other with a liquid crystal layer therebetween. One of the substrates having, thereon, an upper electrode having a plurality of slits formed therein, a lower electrode facing the upper electrode with an insulating film therebetween and disposed so as to be adjacent to the substrate, and an alignment film formed so as to cover surfaces of the upper electrode and the insulating film. Each of the slits includes a linear portion disposed so as to be parallel to a liquid crystal alignment direction when no voltage is applied and two extension portions extending from both ends of the linear portion so that a distance between the two extension portions increases in a direction perpendicular to the linear portion while keeping a symmetrical shape with respect to the direction.Type: GrantFiled: January 20, 2011Date of Patent: February 10, 2015Assignee: Japan Display West Inc.Inventors: Shinichiro Nomura, Kimitaka Kamijo, Tae Nakahara
