Patent number: 8177369Abstract: Laser light beams are diffused and shaped by diffractive optical devices such that they are introduced to corresponding pixels of a liquid crystal layer over an entire area of a display region of a reflective liquid crystal panel. The diffused and shaped laser light beams are introduced to the reflective liquid crystal panel through a field lens and a polarizing beam splitter. Red, green and blue pixels are formed on the reflective liquid crystal panel, and a microlens array is formed on an incoming and outgoing side substrate while reflecting layers corresponding to the pixels are formed on a reflection side substrate. The laser light fluxes of the colors are distributed and condensed by the microlenses and introduced to the corresponding pixels and then reflected by the corresponding reflecting layers. Refractive optical devices may be used in place of the diffractive optical devices.Type: GrantFiled: May 16, 2007Date of Patent: May 15, 2012Assignee: Sony CorporationInventor: Kikuo Kaise

Patent number: 7652739Abstract: A matrix-addressed type liquid crystal display apparatus having switching devices such as TFTs is provided, featuring that an increased effective voltage can be applied without causing hysteresis in V-T characteristics. Namely, by substantially increasing a value of an applicable voltage in excess of which a display defect starts to appear, a high numerical aperture and a high contrast ratio have been achieved at the same time. In the LCD apparatus of the present invention, a gap between adjacent reverse tilt domains each formed in a portion of a pixel which is arranged corresponding to an arbitrary pixel electrode becomes broader than a minimum gap between adjacent pixel electrodes corresponding thereto, or a thickness of a liquid crystal cell in the portion between adjacent reverse tilt domains is set thinner than a thickness of a liquid crystal cell in the portion of the pixel.Type: GrantFiled: October 30, 2006Date of Patent: January 26, 2010Assignee: Sony CorporationInventors: Hisanori Tsuboi, Fumiaki Abe, Katsuhide Uchino, Kazuhiro Noda, Hideshi Sugita, Tadahiro Hagita, Hiromi Fukumori, Syuichi Shima, Kikuo Kaise

Publication number: 20060088668Abstract: In an image display apparatus according to this invention, higher luminance of a displayed image can be realized by a microlens array provided in a liquid crystal display device. The influence of a pre-tilt of liquid crystal molecules in a liquid crystal panel is optically compensated by the optical compensation layer. Higher contrast of the displayed image and a longer life of the apparatus are thus realized. Since a highly light-resistant inorganic material is used for the optical compensation layer, higher luminance of the displayed image can be realized by higher output of a light source of the image display apparatus. Specifically, if sapphire or crystal, which is highly thermally conductive, is used as the inorganic material, rise in the temperature of the liquid crystal display device can be restrained.Type: ApplicationFiled: December 2, 2005Publication date: April 27, 2006Inventors: Tomonori Tsukagoshi, Fumiaki Abe, Kikuo Kaise
