Title:
OPTICAL LAMINATE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/131505
Kind Code:
A1
Abstract:
[Problem] To provide a novel optical laminate in which color defects are suppressed in end sections of a polarizer at high temperature and high humidity. [Solution] An optical laminate having a polarizer and a selectively light-absorbing pressure-sensitive adhesive layer that is laminated in contact with the polarizer, the optical laminate being such that: iodine in the polarizer is oriented in an adsorption orientation, and the boron content of the polarizer is 5.0 mass% or less; and a pressure-sensitive adhesive composition for forming the selectively light-absorbing pressure-sensitive adhesive layer contains a selectively light-absorbing polymer.
