Abstract:
1. A liquid crystal display device, comprising: a liquid crystal cell including a first substrate disposed on an observer side, a second substrate disposed on a backlight side, and a liquid crystal layer sealed between the first substrate and the second substrate; a first polarization member for transmitting light in a predetermined polarization direction, the first polarization member being disposed on the observer side relative to the liquid crystal layer; and a second polarization member for transmitting light in another polarization direction which is orthogonal to the predetermined polarization direction, the second polarization member being disposed on the backlight side relative to the liquid crystal layer, wherein: at least one of the first polarization member and the second polarization member comprises a multilayer thin film polarizer including a plurality of thin film polarizers which are stacked so that transmission axes of the plurality of thin film polarizers are aligned; at least one of the plurality of thin film polarizes in the multilayer thin film polarizer comprises a thin film polarizer formed in a predetermined film thickness by coating with dye molecules which are aligned by a shear stress; the second polarization member includes a second polarizer provided on the backlight side of the second substrate, and a second supplementary polarizer provided so that an absorption axis of the second supplementary polarizer is in parallel to absorption axis second polarizer; and the second polarizer is formed by including the multilayer thin film polarizer.
