There is provided a retardation film including a stretched film of a polymer film having an absolute value of photoelastic coefficient (m2/N) of 50x10-12 or less measured by using light of a wavelength of 550 nm at 23° C., which satisfies the following expressions (1) and (2): Re[450]<Re[550] Rth[550] In the expressions (1) and (2): Re[450], Re[550], and Re[650] respectively represent in-plane retardation values measured by using light of wavelengths of 450 nm, 550 nm, and 650 nm at 23° C.; and Rth[550] represents a thickness direction retardation value measured by using light of a wavelength of 550 nm at 23° C. |
