PURPOSE: An adhesive composition is provided to prevent formation of volatile material, to prevent loss of adhesion, to prevent bubbles under high temperature and high humidity environments, and to have excellent durability. CONSTITUTION: An adhesive composition comprises 100.0 parts by weight of an acrylic copolymer, 0.1-5 parts by weight of an isocyanate-based crosslinking agent, 5-25 parts by weight of a polyfunctional (meth)acrylate monomer, and 0.01-10 parts by weight of a photopolymerization initiator represented by chemical formula 1. In chemical formula 1, X is hydrogen or an C1-10 alkyl group, and n is an integer from 2-50. The average molecular weight of the photopolymerization initiator is 600-4,500 g/mol. The polyfunctional (meth)acrylate monomer is trifunctional or more. The adhesive composition additionally includes 0-10 parts by weight of a silane coupling agent, based on 100.0 parts by weight of the acrylic copolymer. |
