Abstract

Disclosed are: a photocurable adhesive agent which has excellent storage stability, can prevent the discoloration of the adhesive agent itself or a material to be adhered during curing, has a high curing rate, and can provide good adhesion; a polarizing plate using the photocurable adhesive agent; a method for producing the polarizing plate; an optical member; and a liquid crystal display device. Specifically disclosed is a photocurable adhesive agent for adhering a protective film to a polarizer comprising a polyvinyl alcohol resin film having iodine or a dichroic dye adsorbed and oriented thereon. The photocurable adhesive agent comprises: 100 parts by mass of an epoxy resin (A) having two or more epoxy groups in the molecule, wherein at least one of the epoxy groups is an alicyclic epoxy group; 5 to 1000 parts by mass of an epoxy resin (B) having two or more epoxy groups in the molecule and containing substantially no alicyclic epoxy group; and 0.5 to 20 parts by mass of a photo-cationic polymerization initiator (C).
