Abstract
A phase difference film including: a phase difference thin film including at least two non-liquid crystal polymers, wherein the phase difference thin film satisfies refractive indexes of n≥n>nand has a thickness direction phase difference per unit thickness of greater than or equal to about 80 nm/μm, wherein ndenotes a refractive index of the phase difference thin film at a slow axis thereof, ndenotes a refractive index of the phase difference thin film at a fast axis thereof, and ndenotes a refractive index of the phase difference thin film in a direction perpendicular to the slow axis and the fast axis thereof, and wherein an average light transmittance in a wavelength region of about 360 nm to about 740 nm is greater than or equal to about 88%, and a display device including the same.
