Long Phase Difference Film, Long Optical Film, Long Polarizing Film, Manufacturing Method For Long Phase Difference Film, And Manufacturing Method For Long Optical Film

Abstract: A long retardation film (10) including a longitudinal direction (D2) and a lateral direction (D1) is provided with a substrate (20), and a retardation layer (40) superposed on the substrate (20). The retardation layer (40) includes a first region (41) and a pair of second regions (42). The first region (41) is located between the pair of second regions (42) in the lateral direction (D1). The retardation layer (40) includes a cured product of a liquid crystal composition. The second region (42) has a second slow axis (A42). A second orientation angle (?42) between the second slow axis (A42) and the longitudinal direction (D2) is 0° or more but less than 10°, or 170° to 180° exclusive.
