Title:
ADHESIVE LAYER-EQUIPPED POLARIZING FILM, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/188971
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive layer-equipped polarizing film having an odd shape, and capable of reducing occurrence of a crack in a polarizer and preventing peeling and foaming of an adhesive layer and warpage of a polarizing film. This adhesive layer-equipped polarizing film comprises a polarizing film, and an adhesive layer on one surface of the polarizing film. The adhesive layer-equipped polarizing film has an odd shape other than a rectangular shape, and when a strain gauge is attached to a surface not having the adhesive layer of the polarizing film such that a measurement axis and an absorption axis of the polarizing film intersect at right angles and strain amounts are measured, a difference between a strain amount at -40°C and a strain amount at 85°C is 3000 με or less, and the creep value of the adhesive layer at 85°C is 15-600 μm inclusive.
