Beschreibung
Zusammenfassung:	The present invention provides a method for producing a differently shaped polarizing plate, the method being capable of preventing a decrease in durability. The method for producing a differently shaped polarizing plate of the present invention includes a step of forming a differently shaped portion by moving at least one of a rectangular polarizing plate and an end mill blade while the end mill blade is rotated and pressed against the rectangular polarizing plate to cut the rectangular polarizing plate. Preferably, the step is performed while a jig is pressed against the rectangular polarizing plate, at the periphery of a region to be cut.
