Patent number: 6480253Abstract: To manufacture at a good yield a large-screen display having low resistivity of wires and excelling in flatness of substrates, a metal material, a transparent electrode material, and a conductive resin are used for forming either scanning electrodes or signal electrodes, or both of the same. Not less than two materials are used as the metal material, while amorphus ITO is used as the transparent electrode material. An electrode substrate has electrode structures in each of which a metal wire made of the foregoing metal material, a transparent electrode made of the foregoing transparent electrode material, and a conductive resin layer are laminated in this order on a transparent substrate. Conductivity is imparted to the conductive resin layers by conductive particles electrodeposited by the micell electrolytic method.Type: GrantFiled: July 27, 1999Date of Patent: November 12, 2002Assignees: Sharp Kabushiki Kaisha, The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: Mitsuhiro Shigeta, Hideki Uchida, Masahiko Tomikawa, Hisashi Akiyama, Nobuyuki Itoh, Shuji Miyoshi

Patent number: 6266121Abstract: A method of manufacturing a liquid crystal display element includes the steps of (a) forming a spacer having a uniform height on a glass substrate having formed thereon scanning lines, a black matrix, an insulating layer and an alignment layer in an area to which the black matrix is projected in a direction perpendicular to a substrate surface; (b) forming an adhesive layer on a transfer substrate; (c) pressing an upper surface of the spacer against the adhesive layer on the transfer substrate; and (d) selectively applying an adhesive only onto the upper surface of the spacer by the step (c). In the step (a), it is preferable that the spacer be formed so as to have a trapezoidal cross section with respect to a plane perpendicular to the lengthwise direction.Type: GrantFiled: November 24, 1997Date of Patent: July 24, 2001Assignees: Sharp Kabushiki Kaisha, The Secretary of State for Defence in Her Brittanic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: Mitsuhiro Shigeta, Hideki Uchida, Kazuhiko Tamai, Shuji Miyoshi, Masami Kido

Patent number: 5468519Abstract: Methods for forming an orientation film comprising a first step wherein a silane coupling agent is chemically adsorbed on a substrate surface, and a second step wherein an organic compound comprising a functional group capable of coupling with the silane coupling agent is coupled with the silane coupling agent. The second step includes a) applying a magnetic or electrical field in a selected direction to a mixture of 1) a liquid crystal compound being in a liquid crystal phase when heated and 2) the organic compound, b) contacting the substrate with the mixture which is in the applied magnetic or electrical field, and c) heating the mixture which is contacted with the substrate to a temperature sufficient for coupling of the silane coupling agent and the organic compound during the magnetic or electrical field application. The organic compound coupled with the silane coupling agent is directed toward a direction corresponding to the selected direction of the magnetic or electrical field.Type: GrantFiled: December 8, 1993Date of Patent: November 21, 1995Assignee: Sharp Kabushiki KaishaInventors: Hisashi Akiyama, Shuji Miyoshi
