摘要:
A liquid crystal panel of the present invention includes at least a liquid crystal cell, a first polarizer disposed on one side of the liquid crystal cell, a second polarizer disposed on the other side of the liquid crystal cell and a retardation film (A) disposed between the liquid crystal cell and the first polarizer, wherein the retardation film (A) contains a thermoplastic polymer having at least a substituent (a) represented by the following formula (I) and its in-plane retardation value (Re[750]) at a wavelength of 750 nm is larger than its retardation value (Re[550]) at a wavelength of 550 nm. The liquid crystal panel has such an effect that it reduces coloring of characters or images and a color shift even if a screen is viewed from any direction at an angle range of 360°.
