Abstract:
1. A negative C-plate optical anisotropic film comprising a polycycloolefin, wherein the polycycloolefin comprises repeating units derived from compounds represented by the following Chemical Formula 1, and wherein the optical anisotropic film has a retardation value (R th ), defined by the following Equation 1, of 30 to 1000 nm when the film thickness is 30 to 200 μm: wherein n n d is the film thickness: wherein m is an integer from 0 to 4; at least one of R the non-polar functional group is selected from the group consisting of hydrogen; a halogen; a C the polar functional group is selected from the group consisting of a C wherein each R each of R
