  • Publication number: 20120069509
    Abstract: With this method, it is possible to etch a desired surface of a display panel substrate without excesses or deficiencies. A method for fabricating a display panel includes the steps of forming circuit wiring in each of a plurality of areas that are to become display panels on a substrate member, forming protective films (9a, 9b) for covering at least part of the substrate member and the circuit wiring so as to cross a cutting line (c) of the substrate member for separating each of the display panels, separating each display panel by cutting the substrate member along the cutting line (c) after the protective films (9a, 9b) are formed, and etching a cut face of the separated display panel.

  • Patent number: 7253131
    Abstract: The invention provides a curing resin composition to be used for a sealant or an end-sealing material for a display element, which comprises a curing resin together with a photopolymerization initiator and/or a curing agent and, has a carbonyl group derived from a (meth)acryl group together with an epoxy group and/or a hydroxyl group derived from an epoxy group and, a cured product of which has nitrogen atoms at a ratio of 3 to 10% by atom in the total of carbon atoms, hydrogen atoms and nitrogen atoms in the composition; a volume resistance of 1×1013 ?·cm or higher; a dielectric constant of 3 or higher at 100 kHz; and a glass transition temperature of 80 to 150° C.

  • Publication number: 20070021524
    Abstract: It is an object of the invention to provide a curing resin composition that scarcely causes pollution of a liquid crystal owing to elution of its components to the liquid crystal material and therefore, causes little unevenness of color in liquid crystal display in the case of using it as a sealant for a liquid crystal display element or an end-sealing material for a liquid crystal display element in fabrication of a liquid crystal display element and that is excellent in the storage stability and therefore, optimum for fabrication of a display apparatus especially by one drop fill process and to provide a sealant for a display element and an end-sealing material for a display element using the composition.

  • Publication number: 20050087727
    Abstract: A common transfer material is provided that is used for a common transfer electrode provided between electrodes formed adjacently on respective inner sides of paired substrates facing each other. The common transfer material contains a resin and electrically-conductive and has a content of non-electrically-conductive filler that is at least 0 part by mass and at most 1 part by mass with respect to 100 parts by mass of the resin. A liquid-crystal panel using the common transfer material as well as a method of manufacturing the liquid-crystal panel are provided. The common transfer material with which the reliability of the liquid-crystal panel can be improved, the liquid-crystal panel using the common transfer material and the method of manufacturing the liquid-crystal panel can thus be provided.
