<p>PURPOSE: An adhesive composition is provided to have excellent stress-releasing performance and to prevent light leakage when applied to an optical unit such as a polarizer. CONSTITUTION: An adhesive composition comprises a first (meth)acrylic acid ester with the weight average molecular weight of 500,000-3,000,000, a second (meth)acrylic ester polymer with the average molecular weight of 8,000-300,000, and a crosslinking agent. Each of the first and second (meth)acrylic ester polymer does not contain an acidic group substantially, and respectively contains hydroxy group-containing monomers(a,b) which satisfy reactivity with the crosslinking agent: hydroxy group-containing monomer(a) < hydroxy containing monomer(b).</p> |
