Title:
POLARIZING PLATE, METHOD FOR MANUFACTURING POLARIZING PLATE, AND IMAGE DISPLAY DEVICE USING SAID POLARIZING PLATE
Document Type and Number:
WIPO Patent Application WO/2020/230717
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a polarizing plate that has a low decrease in transmittance in high-temperature environments and outstanding durability, even if used in an image display device with an interlayer filling structure; and a method for manufacturing the polarizing plate. Another purpose of the present invention is to provide an image display device which achieves durability with improved display characteristics in high-temperature environments. The present invention provides a polarizing plate characterized by comprising: a polyvinyl alcohol–based resin polarizing element formed by adsorbing and orienting iodine; a layer that contains a urea-based compound, formed on at least one side of the polarizing element and including at least one selected from urea, a urea derivative, thiourea, and a thiourea derivative; and a transparent protective film.
