摘要： PROBLEM TO BE SOLVED: To provide a polarizer with a pressure-sensitive adhesive in which light leakage is improved.SOLUTION: In a view of the present invention, a polarizer with a pressure-sensitive adhesive is so designed as to improve light leakage by making small a distribution of absorption axes after a durability test on the polarizer with the pressure-sensitive adhesive stuck on a glass substrate. In another view, a polarizer with a pressure-sensitive adhesive is so designed as to improve light leakage by setting a distribution of absorption axes at 80°C seven days after a heat-resistance test on a polarizer with a pressure-sensitive adhesive stuck on a glass substrate to a 3 multiple of a standard deviation and 1.3 degree or less. In a further another view, a polarizer with a pressure-sensitive adhesive is so designed as to improve light leakage by setting a difference between a maximum value and a minimum value of absorption axes at 80°C seven days after heat resistance test on the polarizer with the pressure-sensitive adhesive stuck on a glass substrate to 1.5 degree or less.
