Abstract
A polarizing member is constituted by an absorption type polarizing film, and one polymer material layer or two or more polymer material layers provided on one or both of opposite surfaces of the absorption type polarizing film, wherein each polymer material layer does not have any extra ordinary refractive index area with a length not smaller than 20 μm and does not have two or more extraordinary refractive index areas with a length of from 0.5 to 20 μm in a region of 50 μm-radius. An optical member is constituted by a laminate at least having the polarizing member, and a reflection type polarizing plate. A liquid-crystal display device is constituted by either of the polarizing member and the optical member, and a liquid-crystal cell, wherein either of the polarizing member and the optical member is provided on one or both of opposite sides of the liquid-crystal cell.
