Abstract:
1. A photocurable resin composition for forming a resin layer within a display device comprising a display member and an optical member disposed on a front surface of the display member with the resin layer interposed therebetween, the photocurable resin composition comprising: (A) a urethane (meth)acrylate oligomer having a polyoxyalkylene structure, (B) a (meth)acrylic polymer, (C) a (meth)acrylic monomer, and (D) a photopolymerization initiator, wherein the component (A) is produced using three or more monomer components including (a1) at least one polyoxyalkylene polyol, (a2) at least one polyisocyanate, and (a3) at least one hydroxyl group-containing mono(meth)acrylate compound, a relationship N between a total mass n1 of the three or more monomer components and a total equivalent weight n2 of acryloyl groups within the three or more monomer components satisfies a formula shown below, and the component (A) is substantially free of unreacted isocyanate groups, and wherein the component (B) comprises a (meth)acrylic polymer having a carboxyl group, and the component (C) comprises a (meth)acrylic monomer having a carboxyl group.
