METHOD FOR MANUFACTURING POLARIZING PLATE, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for highly efficiently manufacturing a polarizing plate without forming air bubbles having such a dimension as to reduce the quality of a polarizing plate in an adhesive layer, a polarizing plate manufactured by the method, and a liquid crystal display device formed by sticking the polarizing plate to a liquid crystal panel.

SOLUTION: The method for manufacturing the polarizing plate includes: a sticking step for sticking a polarizing film to at least a protective film via the adhesive layer; and an air bubble reducing step for heating the polarizing plate in the atmosphere of pressure of 400kPa to 800kPa and temperature of 50°C to 80°C. This constitution can highly efficiently manufacture the polarizing plate without forming air bubbles in the adhesive layer and thereby increase the productivity and yield of the polarizing plate.
