PURPOSE: A pressure-sensitive adhesive composition is provided to effectively suppress light leakage according to the dimensional change of a polarizer and to obtain an adhesive with excellent adhesive properties, re-stripping properties, and workability. CONSTITUTION: A pressure-sensitive adhesive composition comprises a crosslinkable acrylic polymer in which the average molecular weight is more than 500,000 and less than 1,000,000, and a polyfunctional cross-linking agent. The pressure-sensitive adhesive composition has an interpenetrating polymer network structure in a hardened state. The crosslinkable acrylic polymer is a polymer of a monomer mixture including 80-99.8 parts by weight of a (meth)acrylic acid ester-based monomer and 0.01-10 parts by weight of crosslinkable monomer. The polyfunctional cross-linking agent is one or more selected from the group consisting of an isocyanate compound, epoxy compound, aziridine compound, and metal chelate compound. |
