PHOTOCURABLE RESIN COMPOSITION AND CURED PRODUCT OF SAME; RESIN SHEET AND PRODUCTION METHOD FOR SAME; AND DISPLAY DEVICE

摘要

Disclosed is an adhesive sheet and material for same. The adhesive sheet can be used to laminate a display member and a front surface optical member, has, at a broad spectrum of temperatures, little stress derived from the expansion and contraction of each member and little internal stress from the residual stress during lamination, and is capable of suppressing display variation. A photocurable resin composition contains: (A) a urethane(meth)acrylate oligomer that has a polyoxyalkylene structure; (B) a (meth)acrylic polymer; (C) a (meth)acrylic monomer; and (D) a photopolymerisation initiator. Therein composition (A) is an oligomer that does not substantially contain unreacted isocyanate groups, and is formed from constituent monomers including: (a1) a polyoxyalkylene polyol, (a2) a polyisocyanate, and (a3) a hydroxylated mono(meth)acrylate compound such that the relationship (N) (=n1/n2), where n1 is the total mass of the constituent monomers and n2 is the total equivalent weight number of acryloyl groups present in all of the constituent monomers, is 4000 or greater.
