The present invention relates to an acrylic copolymer composition excellent in heat resistance and light transmittance and capable of exhibiting a high retardation value, an acrylic copolymer formed therefrom, and a retardation film containing the same. Accordingly, the retardation film is excellent in heat resistance and can have a high retardation value. In particular, it is possible to simultaneously exhibit the compensation effect of the A-plate and the C-plate without coating liquid crystal molecules having a negative retardation value . Accordingly, the retardation film according to the present invention can be easily applied to a liquid crystal display device, particularly, an IPS mode liquid crystal display device. |
