Abstract
The present invention discloses a thin phase film exhibiting various optical characteristics, heat-resistance, and adhesion to other materials that thermoplastic norbornene resin has, having a high toughness and an excellent phase characteristic, and easy to handle when processed and used, and also discloses a polarizer comprising this thin phase film. The phase film of the present invention is made of thermoplastic norbornene resin. The phase film is characterized in that if the index of refraction along the in-plane fast axis is denoted by nx, the index of refraction along the in-plane slow axis by ny, the index of refraction in the direction of the film thickness by nz, the thickness of the film by d, the phase difference in the plane of film of the transmitted light having a wavelength lambda in a specific range by α(<λ>), and the phase difference in the direction of the film thickness of the transmitted light having a wavelength lambda nm by β(λ); the phase difference α(550) in the plane of the film of the transmitted light having a wavelength of 550 nm, the phase difference β(550) in the direction of the film thickness of the film of the transmitted light having a wavelength of 550 nm, and the thickness d of the film satisfy specific conditions.
