1. A polarized functional part module for integrating with a liquid crystal display having a liquid crystal layer and a polarizer, PA forward said liquid crystal layer, said functional part module defining vertical and horizontal axes, said functional part module having a module rear surface that may be positioned forward a front surface of said liquid crystal display and a module front surface through which light from said liquid crystal display may exit to a viewer, said module comprising:

  • an EMI shielding functional part comprising a sheet member; and

    a linear polarizer, PB, and a quarter wave retarder, RB,wherein said EMI shielding functional part sheet member is separated from said polarizer, PA,wherein said polarizer, PA is the closest linear polarizer to said liquid crystal layer that is forward said liquid crystal layer, andwherein said module front surface comprises an anti-reflection treatment.
