1. A display system comprising:

  • a transparent plate;

    a liquid crystal display for generating a display light of information, said display light having a plane of polarization inclined by an angle of about 45°

    relative to a vertical axis of an image plane of said liquid crystal display, the display light being incident on a second surface of said transparent plate at Brewster'"'"'s angle and reflected on a side of the second surface of transparent plate to be directed to an eye of an operator; and

    an optical rotation layer disposed to a first surface of said transparent plate, said optical rotation layer being adapted to receive the display light from said liquid crystal display and to optically rotate the plane of polarization of the display light from said liquid crystal display by an angle of about 45° and

    to allow P-polarized light to emanate therefrom.
