Patent ID: 11169312

Abstract:
A pressure-sensitive-adhesive-layer-attached polarizing film is disclosed having an odd shape, and capable of reducing occurrence of a crack in a polarizer and preventing peeling and foaming of a pressure-sensitive adhesive layer and warpage of a polarizing film. This pressure-sensitive-adhesive-layer-attached polarizing film comprises a polarizing film, and a pressure-sensitive adhesive layer on one surface of the polarizing film. The pressure-sensitive-adhesive-layer-attached polarizing film has an odd shape other than a rectangular shape, and when a strain gauge is attached to a surface not having the pressure-sensitive 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 3000με or less, and the creep value of the pressure-sensitive adhesive layer at 85° C. is 15-600 μm inclusive.
