Patent ID: 8865299

Claim:
A retardation film comprising: a) a first acrylic resin layer that does not include rubber component; and b) a second acrylic resin layer that is layered on at least one side of a) the first acrylic resin layer and comprises an acrylic resin and 1 to 20 parts by weight of rubber component based on 100 parts by weight of the acrylic resin, wherein both the first acrylic resin layer and the second acrylic resin layer comprise an acrylic copolymer that comprises an acrylic monomer, a styrene monomer, and a maleic anhydride monomer, wherein the glass transition temperature (T g ) of a) the first acrylic resin layer and b) the second acrylic resin layer is in the range of 100 to 250° C., and wherein a difference between the glass transition temperature (T g ) of a) the first acrylic resin layer and the glass transition temperature (T g ) of b) the second acrylic resin layer is in the range of 0 to 30° C.
