  • CURING RESIN COMPOSITION, SEALING MATERIAL FOR LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE
    Publication number: 20090134358
    Abstract: It is the object of the invention to provide a curable resin composition which causes no liquid crystal contamination, which are excellent in the adhesive property to a glass, and which causes no cell gap inequality in the case it is used as a sealant for a liquid crystal display element to produce a liquid crystal display element by a one drop fill process, a sealant for a liquid crystal display element, and a liquid crystal display element. The invention is a curable resin composition, which contains a curable resin to be cured by light and/or heat and a polymerization initiator, the curable resin being a crystalline (meth)acrylic acid-modified epoxy resin comprising a (meth)acrylic group and an epoxy group in one molecule.
    Type: Application
