摘要： The present invention relates to an optical film that is excellent in optical properties and can be produced at low cost. In the optical film formed by laminating a transparent polymer film layer and a birefringent layer of a non-liquid crystalline polymer, the birefringent layer satisfies a condition represented by nx≧ny>nz and the in-plane retardation of the transparent polymer film layer is 50 nm or less. In the above formula, nx, ny and nz are the refraction indices in the X-, Y- and Z-axes directions of the birefringent layer, respectively. The X-axis direction is the axial direction in which the refraction index shows a maximum value in the in-plane direction of the birefringent layer, the Y-axis direction is the axial direction perpendicular to the X-axis direction in the plane, and the Z-axis direction is the thickness direction perpendicular to the X- and Y-axes directions.

摘要： A method for preparing an optical film, which comprises applying and developing an application liquid mixture containing a liquid crystal monomer, a chiral agent and a polymerization initiator on an orientation substrate, subjecting the resultant developed layer to a heat treatment, to orient the monomer to a cholesteric structure, and then subjecting the developed layer to a poltmerization treatment, to polymerize the oriented liquid crystal monomer, thereby forming an optical film exhibiting a selective reflection wave length of 100 to 320 nm. An optical film prepared by the above method is reduced in the coloring due to selective reflection.
