1. , a kind of display device (200) that is configured to provide the two and three dimensions impression, it comprises display panel (230), back lighting device (201,300,400) and control circuit (232), wherein, described back lighting device comprises:

  • The optical clear photoconduction, it has;

    First side, it is used for being coupling in the light that transmits along first direction in the described photoconduction in described photoconduction,With the described first side second side surface opposite, it is used for being coupling in the light that transmits along the second direction opposite with described first direction in the described photoconduction in described photoconduction;

    Exit surface, the light that is coupled in the described photoconduction is coupled to outside the described photoconduction by described exit surface;

    AndPolarization with relief fabric is selected the beam splitting interface, it is used for from isolating first beam with first polarization along the light of described first direction transmission, and described first beam redirected, thereby described first beam is penetrated from described exit surface with first angle, and from have second light beam of first polarization along separation the light of described second direction transmission, and described second beam redirected, thereby make described second beam with second angle that is different from described first angle from described exit surface outgoing;

    AndWherein, dispose described control circuit and provide three-dimensional impression to adopt described first and second beams.
