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 μm or less.
