摘要： The retardation film of the present invention contains a thermoplastic polymer having at least a side chain component (A) oriented in a direction substantially orthogonal to a slow axis, and the absorption edge wavelength (λcut-off) of the side chain component (A) is 330 nm or more, and an in-plane retardation value (Re[450]) at a wavelength of 450 nm is smaller than that (Re[650]) at a wavelength of 650 nm. In the above-mentioned retardation film, the difference (ΔRe650−450=Re[650]−Re[450]) between the in-plane retardation value (Re[650]) at a wavelength of 650 nm and the in-plane retardation value (Re[450]) at a wavelength of 450 nm is preferably 10 nm or more.The retardation film of the present invention exhibits optical characteristics in which the in-plane birefringence is large and the difference between a retardation value on the short wavelength side and a retardation value on the long wavelength side is large.
