Title:
POLARIZING FILM, POLARIZING FILM WITH ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216598
Kind Code:
A1
Abstract:
The present invention is a polarizing film which has a first resin film on one surface of a polarizer having a thickness of 10 μm or less, while having a second resin film on the other surface of the polarizer, and which is configured such that: the water vapor permeabilities of the first resin film and the second resin film are 100 g/(m2·day) or less; and at least the first resin film among the first resin film and the second resin film has a breaking stress of 13 N or more and an elongation at break of 2.5 mm or more in a direction orthogonal to the absorption axis of the polarizer. Since a polarizing film according to the present invention comprises resin films having low water vapor permeabilities on both surfaces of a polarizer having a thickness of 10 μm or less, deterioration of the polarizer due to humidification is suppressed (good reliability in terms of humidification) and occurrence of through cracks is able to be suppressed even in an environment under severe thermal shock.
