PURPOSE: A binder for adhesive is provided to maintain excellent durability, reworkability, and adhesion in high temperatures and high humidity, and to improve light-leakage phenomenon. CONSTITUTION: A binder for adhesive comprises an acrylic copolymer comprising an aromatic group, and pyrrolidone group, and cellulose based resin. The acrylic copolymer is polymerized from a monomer mixture comprising aromatic (meth)acrylate and N-vinyl pyrrolidone. The weight average molecular weight of the acrylic copolymer is 100,000-500,000 g/mol. The glass transition temperature(Tg) is (-30) - 20°C. The weight average molecular weight of the cellulose based resin is 10,000 - 100,000 g/mol. |
