摘要：The present invention relates to a method for measuring boric acid included in the surface of a polarizing plate, and more specifically, to a method for measuring boric acid included in a polarizing plate, wherein the method enables accurate measurement of boric acid included in a manufactured polarizing plate by including a step of obtaining a polarizing plate piece in which unreacted boric acid is exposed to the outside by physically crushing a polarizing plate having unreacted boric acid on the surface thereof and a step of putting the polarizing plate piece into a diol solution which is formed by dissolving a diol in a solvent which does not dissolve the polarizing plate.
