Title: POLARIZING FILM AND IMAGE DISPLAY DEVICE
Abstract:
The present invention is a polarizing film in which a resin film is provided to at least one surface of a polarizer, wherein an elution component is generated from the resin film when the resin film is left for 300 hours in heat and humidity conditions of 85°C and 85% RH, and a transparent blocking layer for suppressing the migration of the elution component to the polarizer side is provided between the polarizer and the resin film. This polarizing film is capable of preventing the reduction of optical properties even in high temperature, high humidity environments.
