Patent number: 6266113Abstract: A reflection type liquid crystal display device according to the present invention is constructed to include: a light modulation layer having a light scattering state changed when a voltage is applied between electrode faces; at least one kind of color separation layer arranged at the back of the liquid crystal; and a reflection layer arranged at the back of the color separation layer. The light modulation layer is a polymer network type polymer scattered liquid crystal layer or a phase conversion type liquid crystal layer, and the color separation mirror is a cholesteric liquid crystal polymer layer or a dielectric multi-layered thin film characterized to reflect a light within a predetermined wavelength range in the visible light region selectively. A reflection preventing layer and an ultraviolet ray cut-off layer are further arranged on the surfaces of the electrode faces.Type: GrantFiled: June 19, 1997Date of Patent: July 24, 2001Assignee: Seiko Instruments Inc.Inventors: Osamu Yamazaki, Shunichi Motte, Teruo Ebihara, Shigeru Senbonmatsu, Kaori Taniguchi, Takakazu Fukuchi, Hiroshi Sakama, Masafumi Hoshino, Naotoshi Shino, Shuhei Yamamoto

Patent number: 6215536Abstract: A reflective liquid crystal display device comprises a transparent first substrate having formed thereon a transparent electrode, a first filter having a first color, and a second filte having a second color. A second substrate is disposed opposite and spaced-apart from the first substrate. A reflection layer is disposed on the second substrate. A polymer dispersed liquid crystal layer is disposed between the transparent electrode and the reflection layer and is formed by exposure to an ultraviolet ray in a preselected wavelength range. A ratio of a transmissivity of the first filter for the ultraviolet ray to a transmissivity of the second filter for the ultraviolet ray is 3.0 or less.Type: GrantFiled: January 7, 1999Date of Patent: April 10, 2001Assignees: Seiko Instruments Inc., Seiko Precision Inc.Inventors: Teruo Ebihara, Shunichi Motte, Kaori Takano, Shigeru Sembonmatsu, Hiroshi Sakuma, Takakazu Fukuchi, Osamu Yamazaki, Masafumi Hoshino, Naotoshi Shino, Shuhei Yamamoto, Masanori Fujita

Patent number: 5990995Abstract: A reflection type liquid crystal display device comprises a pair of substrates having electrodes, a light scattering type liquid crystal layer interposed between the substrates, a reflection layer disposed over a rear surface of the light scattering type liquid crystal layer, and a light absorbing layer disposed over a rear surface of the reflection layer for absorbing a light passed through the reflection layer. The light scattering type liquid crystal layer changes into a scattering state or a transparent state in accordance with a change in a voltage level between the electrodes, and transmits 60% or more of incident light irrespective of the change in the voltage level between the electrodes. The reflection layer has a reflectivity within a range of 10 to 50% for reflecting a forward scattered light passed through the light scattering type liquid crystal layer.Type: GrantFiled: June 18, 1997Date of Patent: November 23, 1999Assignee: Seiko Instruments Inc.Inventors: Teruo Ebihara, Osamu Yamazaki, Shunichi Motte, Shigeru Senbonmatsu, Kaori Taniguchi, Naotoshi Shino, Shuhei Yamamoto, Hiroshi Sakama, Masafumi Hoshino, Takakazu Fukuchi

Patent number: 4599246Abstract: A thin film transistor array for a liquid crystal display device is produced by simultaneously forming gate electrodes and picture element electrodes; forming islands of a layered structure comprised of a gate insulating film, a thin semiconductor film and a light shielding film in a single masking step; and forming the gate, source and drain wiring metals in contact windows by the "lift-off" technique after using a resist film for opening the contact windows. Only three masking steps are required thereby enabling an increase in production yield and a lower production cost as compared to conventional techniques which typically require seven masking steps.Type: GrantFiled: October 29, 1984Date of Patent: July 8, 1986Assignee: Seiko Instruments & Electronics Ltd.Inventors: Toshihiko Harajiri, Shunichi Motte, Masafumi Shinbo
