摘要

A patterned phase difference film has an optically anisotropic layer alternately having a first phase difference region and a second phase difference region, in which the first phase difference region and the second phase difference region contain rod-like liquid crystals or discotic liquid crystals in the form of a hybrid alignment with mutually opposite rising directions of tilt angles, and has a hybrid alignment in which directions of in-plane slow axes and absolute values of in-plane phase differences of the first phase difference region and the second phase difference region are equal in a range of 54 to 74 nm, and in each of the first phase difference region and the second phase difference region, one of an absolute value of a phase difference at a polar angle of 40° and an absolute value of a phase difference at a polar angle of −40° is 135 to 353 nm and the other is 8 to 28 nm.
