Patent number: 10627662Abstract: A panel module includes a bonding resin layer between a first main face of a first substrate and a second main face of second substrate, and a bond made of cured adhesive. At least a part of an outer end face of the bonding resin layer is located inner than an outer end face of the first substrate and an outer end face of the second substrate. The bond has a stronger bonding force and a higher elasticity than the bonding resin layer. The bond is attached to a first region of the first main face and a second region of the second main face in an area outer than the bonding resin layer. The bond is attached to a third region of the outer end face of the second substrate and a fourth region of the first main face.Type: GrantFiled: November 1, 2018Date of Patent: April 21, 2020Assignee: TIANMA JAPAN, LTD.Inventors: Akira Fujita, Akira Suzuki, Yoshiro Kitagawa

Patent number: 8199309Abstract: Disclosed is a liquid crystal display device that includes a TFT substrate. A plurality of gate lines and a plurality of common lines extend in a first direction on the TFT substrate. Drain lines extend in a second direction substantially perpendicularly to these lines. Bus lines are located outside a display area and are extending parallel to the drain lines. Common line terminals are provided on either side of each block that is constituted by a predetermined number of gate terminals. The common line terminals and the lead lines therefore are formed on the same layer as the drain lines and are connected to the bus lines on the same layer without any contacts being used. Resistance along the routes taken by common lines can be reduced.Type: GrantFiled: August 18, 2009Date of Patent: June 12, 2012Assignee: NEC CorporationInventors: Takayuki Konno, Satoshi Inada, Yoshiro Kitagawa, Shinichi Nishida

Patent number: 8102487Abstract: A LCD device includes first and second LCD panels stacked one on another. Each of the first and second LCD panels includes a pair of transparent substrates, a liquid crystal layer sandwiched therebetween, and a pair of polarizing films sandwiching therebetween the pair of transparent substrates. A light diffusion layer having light diffusion function is interposed between the first LCD panel and the second LCD panel. The light diffusion layer reduces the intensity of the light passed by the first LCD panel, thereby alleviating the periodicity of the arrangement of dark areas and bright areas to alleviate the moire caused by light interference.Type: GrantFiled: December 6, 2010Date of Patent: January 24, 2012Assignee: NLT Technologies, Ltd.Inventors: Yoshiro Kitagawa, Hidenori Ikeno, Shinichi Uehara, Takashi Yatsushiro
