摘要：
The present invention provides a method of manufacturing a polarizing plate having sufficient heat resistance, without deteriorating the dye-affinity and the like of the polarizing film and without the necessity of transferring or detaching the polarizing film. Provided is a method of manufacturing a polarizing plate (10) that includes a polyester resin base (11) and a polarizing film including a polyvinyl alcohol resin laminated on the polyester resin base. The method includes the steps of: stretching a laminate that includes a polyvinyl alcohol resin layer (12) laminated on the polyester resin base (11); dyeing the polyvinyl alcohol resin layer (12); and crystallizing the polyester resin base (11). The crystallization step is performed after the dyeing step.
