A pressure-sensitive adhesive layer for optical films. The pressure-sensitive adhesive layer can prevent light leakage caused by stress associated with dimensional change of a component such as an optical film, that has reworkability, and that has satisfactory processability. A pressure-sensitive adhesive optical film produced using the layer is also provided. The pressure-sensitive adhesive layer is prepared with the use of a composition which includes a (meth)acrylic polymer including (a) 34 to 94% by weight of an alkyl (meth)acrylate monomer unit, (b) 5 to 50% by weight of an aromatic ring-containing (meth)acrylate monomer unit, and (c) 0.01 to 0.5% by weight of an amino group-containing (meth)acrylate monomer unit; 0.01 to 2 parts by weight of a peroxide as a crosslinking agent; and 0.01 to 2 parts by weight of a silane coupling agent based on 100 parts by weight of the (meth)acrylic polymer.
