  • Multi-layer sheet and liquid crystal display device
    Patent number: 7198831
    Abstract: The curable pressure-sensitive adhesive sheet A of this invention comprises an optically transparent substrate on which the curable pressure-sensitive adhesive layer 2 is layered on and integrated therewith. The curable pressure-sensitive adhesive layer 2 comprises a curable pressure-sensitive adhesive composite comprising a cationically-polymerizable compound, a polymer and a photocationic polymerization initiator. Surface roughness Rt of a surface of the curable pressure-sensitive adhesive layer is 2 ?m or less.
    Type: Grant
    Filed: January 24, 2005
    Date of Patent: April 3, 2007
    Assignee: Sharp Kabushiki Kaisha
