1. An apparatus for displaying images on a liquid crystal display having partitionable selectively visible regions, comprising:

  • first polarizing means for forming planer polarized light background from incident light;

    a liquid crystal display panel for forming images cross-polarized with polarized light background in substantially parallel alignment with said first polarizing means having a front side displaying said images;

    moveable polarizing means for selectively covering at least a region of liquid crystal display panel, disposed in substantially parallel alignment with said liquid crystal display panel, disposed at the front side of said liquid crystal display panel, opposite said first polarizing means;

    remote polarizing means disposed away from said liquid crystal display having polarization relative to said movable polarizing means which is one of planar-polarization or cross-polarization;

    said remote polarization means operative for enabling a viewer looking through said remote polarizing means to view said images both covered and uncovered by said movable polarizing means; and

    wherein said regions uncovered by said movable polarizing means are invisible for viewing without said remote polarizing means;

    moving means connected to said movable polarizing means for displacing said movable polarizing means.
