<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a polarizing plate having a processed end face with good processability, by which an end face of a polarizing plate can be processed without causing peeling of a (meth)acrylic resin film as a protective film, decrease in impact resistance of the end face after end face processing is suppressed and the (meth)acrylic resin film is prevented from peeling.SOLUTION: A method for manufacturing a polarizing plate having a processed end face includes: a step of stacking a plurality of rectangular polarizing plates each having a (meth)acrylic resin film on a polarizing film to obtain a polarizing plate stacked body having exposed end faces; and a step of cutting the end faces of the polarizing plate stacked body by moving a cutting tool having n of cutting blades relative to the polarizing plate stacked body. In the method, the end face is cut with the cutting tool to satisfy the following conditions: (a) contact times of the n cutting blades with the end face is 200 to 1500 times per 100 mm length in a longitudinal direction of the end face; and (b) a cutting depth cut by one time of the relative movement is 0.3 mm or less.</p> |
