The present invention provides a pattern retardation film having a high orientation as compared with the conventional light. Pattern retardation film (2) is heated and dried layer to form a stacked body forming step of applying a layer composition on the base material (11) oriented pattern, to form a laminate and then dried heating the composition heated and dried layer (12 ") retardation layer comprising a forming step, the pattern alignment layer formation step of forming a heat-drying layer 12 'pattern the alignment layer 12 is irradiated with polarized light pattern with respect to a rod-shaped compounds on the pattern alignment layer 12 ( 13) it is prepared via the retardation layer formation step of forming a. After forming the heat-drying process layer, an exposure time of the air between steps for the retardation layer forming step, heat drying layer 12 'and the pattern alignment layer 12 is less than 4 hours. In order to shorten the exposure time, after the formation of the heat-drying layer 12 'formed or patterned orientation layer 12 of, and may be wound, a layered product into a roll, after forming heat drying lamination process, up to the retardation layer formation step It may be continuously performed in the same manufacturing line.
