A polarization separating film is provided, including an isotropic layer having a refractive index which is the same with respect to light having a first polarization and with respect to light having a second polarization, perpendicular to the first polarization; an anisotropic layer disposed on an upper surface of the isotropic layer and having a first refractive index with respect to light having the first polarization and a second refractive index, different from the first refractive index, with respect to light having the second polarization; a first micropattern disposed on a lower surface of the isotropic layer which changes an optical path of incident light; and a second micropattern, disposed on an interface between the isotropic layer and the anisotropic layer, which totally reflects light having the first polarization and which transmits light having the second polarization.
