Photocurable adhesive composition

A method for manufacturing a liquid crystal panel employing a photocurable adhesive composition, the method comprising:

• (i) arranging a solid sheet or film of an uncured photocurable adhesive composition between a liquid crystal panel and a cover panel of the liquid crystal panel in preparation of forming a bond, wherein the uncured photocurable adhesive composition is solid at 25° C. and melts at a temperature in a range of 40° C. to 80° C.;
• (ii) heating the uncured photocurable adhesive composition to a temperature in a range of 40° C. to 80° C. at which the uncured photocurable adhesive composition melts, whereby a melted uncured photocurable adhesive composition between the liquid crystal panel and the cover panel of the liquid crystal panel is provided;
• (iii) irradiating the melted uncured photocurable adhesive composition with an active energy ray, whereby the uncured photocurable adhesive composition becomes a cured photocurable adhesive composition that bonds with the liquid crystal panel and the cover panel of the liquid crystal panel to provide a manufactured liquid crystal panel;
• wherein the photocurable adhesive composition comprises:
• (A) 100 parts by mass of a urethane(meth)acrylate oligomer having a weight-average molecular weight in a range of 20,000 to 100,000, which is a reaction product of polycarbonate diol produced by copolymerizing 1,6-hexanediol, 1,5-pentanediol, and dialkyl carbonate having one to six carbon atoms, an organic isocyanate compound having at least two isocyanate groups per molecule, an (meth)acrylate having at least one hydroxyl group per molecule;
• (B) 5 parts to 70 parts by mass of an unmodified phenoxy resin having a weight-average molecular weight in a range of 30,000 to 70,000;
• and
• (C) 0.1 parts to 10 parts by mass of a photopolymerization initiator.
