Claim:
1. A method for manufacturing a patterned phase difference film comprising: forming a laminate by coating a substrate with a pattern alignment layer composition for forming a pattern alignment layer containing a photo-alignment material exhibiting a photo-alignment property through irradiation of polarized light; forming a heat-dried layer by heating and drying the pattern alignment layer composition after the forming of the laminate and then immediately winding the laminate in a roll shape without taking a pause in time; within four hours of winding the laminate in a roll shape, extracting the laminate in a sheet shape and immediately forming a pattern alignment layer having a different photo-alignment property by irradiating the heat-dried layer with a polarized light pattern; and forming a phase difference layer containing a rod-like compound having a polymerizable functional group in a molecule exhibiting liquid crystal characteristics on the pattern alignment layer after the forming of the pattern alignment layer.
