Patent number: 7973893Abstract: The present invention is a method of manufacturing a liquid crystal display device, wherein light having an exposure energy is irradiated on the surface of a photo-sensitive resin layer having a predetermined film thickness, and a distribution of thermal deformation characteristics in the thickness direction (or the plane direction) of the photo-sensitive resin layer is formed, then heat treatment is performed to form random undulation (micro-grooves or micro-wrinkles) on the surface of the photo-sensitive resin layer.Type: GrantFiled: November 26, 2008Date of Patent: July 5, 2011Assignee: Sharp Kabushiki KaishaInventors: Naoshige Itami, Tetsuya Fujikawa, Atuyuki Hoshino

Patent number: 7697106Abstract: A liquid crystal display device of the present invention has a structure in which vertically aligned liquid crystal is sealed between a TFT substrate and a CF substrate. Pixel electrodes in which slits are provided are formed on the TFT substrate, while cell gap holding spacers and domain defining projections are formed on the CF substrate. For example, positive type photoresist is coated on a common electrode. Then, first exposure is executed by using a mask for light-shielding spacer forming regions and projection forming regions, and then second exposure is executed by using a mask for light-shielding the spacer forming regions. Then, the photoresist is developed. Accordingly, the spacers and the projections, each having a different height, can be formed simultaneously.Type: GrantFiled: January 12, 2001Date of Patent: April 13, 2010Assignee: Sharp Kabushiki KaishaInventors: Manabu Sawasaki, Takashi Takagi, Yoji Taniguchi, Hiroyasu Inoue, Susumu Nakano, Tomonori Tanose, Naonobu Matsui, Kazuyuki Hosokawa, Kazuhiko Sumi, Masahiro Ikeda, Naoshige Itami

Patent number: 7692740Abstract: The invention relates to a substrate for a liquid crystal display used in a display section of an information apparatus, a liquid crystal display having the same, and a method of manufacturing the same. There is provided a substrate for a liquid crystal display which achieves good display quality with reduced manufacturing steps, a liquid crystal display having the same, and a method of manufacturing the same. TFTs are formed on a glass substrate. A protective film is formed on the TFTs, and a resist pattern is formed on the protective film, the resist pattern having openings located above source electrodes, gate bus line terminals, and drain bus line terminals. The resist pattern is baked at a baking temperature of 200 (or more after irradiating the surface thereof with ultraviolet light to form a wrinkled resin layer having a wrinkled surface.Type: GrantFiled: February 23, 2005Date of Patent: April 6, 2010Assignee: Sharp Kabushiki KaishaInventors: Seiji Doi, Tetsuya Fujikawa, Naoshige Itami, Yoshinori Tanaka, Atsuyuki Hoshino, Yoshio Kurosawa

Patent number: 5975098Abstract: A substrate rinsing apparatus of a non-contact type having a high rinsing ability. An ultrasonic rinsing nozzle and a high-pressure rinsing nozzle are both disposed within the same rinsing apparatus. The ultrasonic rinsing nozzle ejects ultrasonic rinsing liquid as a curtain through a slit, while the high-pressure rinsing nozzle ejects a high-pressure rinsing jet toward the ultrasonic rinsing liquid which is ejected toward a substrate. Not only is foreign matter removed by ultrasonic rinsing, but foregoing matter is removed by the high-pressure rinsing jet and is carried away by a flow of the ultrasonic rinsing liquid and washed off the substrate toward a downstream side of rotation of the substrate.Type: GrantFiled: December 17, 1996Date of Patent: November 2, 1999Assignees: Dainippon Screen Mfg.
