Abstract:
An optical film is provided and has retardations satisfying relations (1) to (3): 0≦Re(550)≦10 (1); −25≦Rth(550)≦25 (2); and |I|+|II|+|III|+|IV|>0.5(nm) (3), with definitions: I=Re(450)−Re(550); II=Re(650)−Re(550); III=Rth(450)−Rth(550); and IV=Rth(650)−Rth(550), wherein Re(450), Re(550) and Re(650) are in-plane retardations measured with lights of wavelength of 450, 550 and 650 nm, respectively; and Rth(450), Rth(550) and Rth(650) are retardations in a thickness direction of the optical film, which are measured with lights of wavelength of 450, 550 and 650 nm, respectively.
