Patent number: 8144301Abstract: When a columnar spacer is provided in a region overlapping with a TFT, there is a concern that pressure will be applied when attaching a pair of substrates to each other, which may result in the TFT being adversely affected and a crack forming. A dummy layer is formed of an inorganic material below a columnar spacer which is formed in a position overlapping with the TFT. The dummy layer is located in the position overlapping with the TFT, so that pressure applied to the TFT in a step of attaching the pair of substrates is distributed and relieved. The dummy layer is preferably formed of the same material as a pixel electrode so that it is formed without an increase in the number of processing steps.Type: GrantFiled: September 24, 2007Date of Patent: March 27, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Saishi Fujikawa, Kunio Hosoya

Patent number: 8139196Abstract: The invention relates to a liquid crystal display element, a method of manufacturing the element, and electronic paper having the element. The invention provides a liquid crystal element in which a change in a state of display attributable to an external force can be suppressed, a method of manufacturing the element, and electronic paper having the element. One blue pixel region is surrounded by four wall structures and four polymer layers without any discontinuity. The wall structures are formed on a bottom substrate and are in contact with a top substrate. The polymer layers are formed by injecting a cholesteric liquid crystal and polymeric substances (monomers or oligomers) which are materials different from both of the cholesteric liquid crystal and the wall structures between the top and bottom substrates and polymerizing the polymeric substances.Type: GrantFiled: March 26, 2009Date of Patent: March 20, 2012Assignee: Fujitsu LimitedInventor: Toshiaki Yoshihara

Patent number: 8102498Abstract: The present invention provides a liquid crystal display device realizing improved reliability by preventing occurrence of a pixel defect. A liquid crystal display includes first and second substrates. A spacer maintains a distance between the first and second glass substrates. A liquid crystal layer is provided between the first and second substrates. A pixel electrode film and a common electrode film are formed over a base insulation film of the first substrate so as to sandwich a pixel insulation film in between. The common electrode film, the pixel electrode film or both of them are partly removed in a region corresponding to the spacer, and the pixel insulation film is partly removed in that region. It prevents the film structure from being broken due to deformation of the base insulation film made of a soft material caused by a pressure applied onto the spacer.Type: GrantFiled: August 24, 2009Date of Patent: January 24, 2012Assignee: Sony CorporationInventors: Yasuhiro Kanaya, Keiichi Yagi
