摘要

本发明中提供一种偏光板之保管方法及制造方法，其系包含：准备含有偏光片及在偏光片上积层之保护薄膜的偏光板，该偏光板为在23℃、相对湿度55%之环境下保管了1周时，在任意边上会产生高度超过3mm之皱褶缺陷、或在任意边上会产生3个以上皱褶缺陷的偏光板之步骤；以及在使保管后的偏光板含水率会变得低于在23℃、相对湿度55%之环境下保管了1周时之偏光板含水率之环境下保管前述偏光板的保管之步骤。 The present invention provides a method for storing and producing a polarizing plate, which comprises: a step of providing a polarizing plate containing a polarizer and a protecting film laminated on the polarizer, the polarizing plate will have a wrinkle defect with a highness over 3 mm on any of the edges, or have 3 or more wrinkle defects on any of the edges after being stored in an environment with a relative humidity 55% at 23℃; and a step of storing the polarizing plate in an environment which allows the moisture content of the polarizing plate after storage to be lower than the moisture content after stored in an environment with a relative humidity 55% at 23℃
