Photocurable adhesive composition
Provided is a method of manufacturing a liquid crystal panel employing a photocurable adhesive composition which causes no damage to adherends during bonding and which, when used in bonding rugged adherends, can bond the adherends without forming a gap therebetween. The photocurable adhesive composition of the inventive method comprises (A) 100 parts by mass of a urethane (meth)acrylate oligomer having a weight-average molecular weight of 20,000 to 100,000, (B) 5 parts to 70 parts by mass of a phenoxy resin, and (C) 0.1 parts to 10 parts by mass of a photopolymerization initiator. The uncured composition has a loss tangent (loss modulus/storage modulus) of less than 1 at 25° C. and the temperature at which the loss tangent of the uncured composition reaches 1 or more is 80° C. or less.
