POLARIZER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a polarizer by which a beautiful picture whose color contrast and hue are not deteriorated and which is not blurred can be realized for a long period of time even when the polarizer is used as a liquid crystal display element under a condition of high temperature and high humidity for a long period of time. SOLUTION: This polarizer is manufactured by impregnating and letting adsorbe a polarizing element in a polymer film in a supercritical state.
