POLARIZING FILM AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/221320
Kind Code:
A1
Abstract:
The present invention is a polarizing film provided with a polarizer and a first transparent layer on both surfaces of the polarizer, wherein the sorbed water content of the first transparent layer is less than the sorbed water content of the polarizer, and the first transparent layer functions as a permeation membrane for assisting with the elimination of moisture in the polarizer. This polarizing film is capable of preventing a decrease in the degree of polarization at the edge of the film even in high temperature, high humidity environments.
