Patent number: 8310614Abstract: A liquid crystal display device preventing a liquid crystal display panel from damage by bending of a light-transmissive substrate and capable of curving a display surface of the panel is provided. The liquid crystal display device comprising: a liquid crystal display panel having a liquid crystal layer sealed between a pair of light-transmissive substrates having pixel formation electrodes on inner surfaces thereof, and formed by assembling positive and negative curved surfaces with respect to one direction; a backlight mounted on a rear surface of the panel along a curved shape of the panel and having at least one light emission device irradiating illumination light toward the rear surface; and a resin member held in a space between peripheral portions where the panel is opposed to the backlight, and fixing and holding a curved state, is provided. Distortion of the light transmissive glass substrates by bending of the panel is eased.Type: GrantFiled: August 7, 2008Date of Patent: November 13, 2012Assignees: Hitachi Displays, Ltd., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Susumu Sasaki, Hitoshi Azuma, Takao Ebine, Tomio Yaguchi, Shoichi Uchino, Akiko Iwata

Patent number: 8089605Abstract: A liquid crystal display panel includes an inorganic thin film which constitutes at least transistors, electrodes and lines. A first substrate includes a first inner surface which faces a second substrate in an opposed manner and a first outer surface on a side thereof opposite to the second substrate. The second substrate includes a second inner surface which faces the first substrate in an opposed manner and a second outer surface on a side thereof opposite to the first substrate. The inorganic thin film is formed on the first or second inner surface in a close contact manner. The center of a thickness ranging from the first outer surface to the second outer surface is positioned inside the second substrate. The relationship of T1+D<T2 is established among a thickness T1 of the first substrate, a thickness T2 of the second substrate, and a distance D between the first and second inner surfaces.Type: GrantFiled: October 21, 2009Date of Patent: January 3, 2012Assignees: Hitachi Displays, Ltd., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Tetsuya Nagata, Hitoshi Azuma, Susumu Sasaki, Takao Ebine, Katsuyuu Takahashi

Patent number: 7903192Abstract: The invention provides a display device which can reduce breaking of a TFT substrate at the time of connecting a wiring member to the TFT substrate after decreasing a thickness of the TFT substrate and a manufacturing method of the display device. A TFT substrate and a counter substrate are adhered to each other to form a display panel. After connecting a wiring member to a line connection portion of the display panel, a portion of the display panel to be etched is masked. An etching protective film formed of an organic film is applied to the masked display panel by coating. Thereafter, a mask is peeled off together with the etching protective film formed on the mask and the display panel is immersed in an etchant thus polishing an exposed surface of a glass substrate to a predetermined thickness. Thereafter, a chemical polishing protective film formed on a wiring member is removed.Type: GrantFiled: August 12, 2008Date of Patent: March 8, 2011Assignee: Hitachi Displays, Ltd.Inventors: Hitoshi Azuma, Susumu Sasaki, Takao Ebine, Tomio Yaguchi, Shoichi Uchino, Akiko Iwata

Publication number: 20100073593Abstract: A first outer surface is a convex surface, and constitutes a first cylindrical surface drawn by moving a first curved line defined on a flat surface P in the direction perpendicular to the flat surface P. A second outer surface is a concave surface and constitutes a second cylindrical surface drawn by moving a second curved line defined on the flat surface P in the direction perpendicular to the flat surface P. The second outer surface includes a pair of end areas drawn by moving the respective end portions of the second curved line and extending toward a middle side beyond the respective areas opposed to the seal, and a middle area drawn by moving the middle portion between the pair of end areas. The second support presses the pair of end areas, while avoiding the middle area.Type: ApplicationFiled: September 22, 2009Publication date: March 25, 2010Inventors: Susumu SASAKI, Hitoshi Azuma, Takao Ebine, Katsuyuu Takahashi, Tetsuya Nagata, Shigeki Nishizawa
