1. image display device comprises:

  • Back light unit, wherein its bottom is equipped with reflecting plate;

    Polarization plates, it is the light of the particular polarization of transmission from the light of described back light unit emission only;

    Polarization converter, its change incide the polarisation of light direction of polarization converter;

    Birefringent element array, this birefringent element array forms by alternately arranging a plurality of first and second birefringence elements, it changes the polarisation of light direction that incides on first and second birefringence elements respectively, so that it is vertical mutually to see through the polarisation of light direction of first and second birefringence elements;

    Reflective polarizer, its only transmission see through the light of the particular polarization in the light of described birefringent element array, and the light of other polarization direction in the light of the described birefringent element array of reflecting ﹠

    transmitting;

    Lens arra, its light that will incide lens arra is divided into first vision area and second vision area;

    WithDisplay panel, its display image.
