摘要： Provided are a cutting information determination method that can use a simpler process to improve yield, and a strip-shaped polarizing sheet manufacturing method using such a method, an optical display unit manufacturing method using such a method, a strip-shaped polarizing sheet, and a polarizing sheet material. A cutting position in the width direction A2, in which a polarizing sheet material MP is to be cut along its longitudinal direction A1, is determined based on the numbers of defects counted with respect to plural points in the width direction A2 of the polarizing sheet material MP. This makes it possible to determine the cutting position in such a way that a region with many defects does not fall within the cut width, so that a higher-yield cutting position can be determined. The cutting position can also be determined using a simple process in which defects are counted with respect to plural points in the width direction A2.
