1. A stereoscopic display device, comprising:

  • a display panel for displaying 2D images and 3D images;

    a driving circuit module; and

    a light-splitting device coupled to the display panel to separate light emitted from the display panel displaying the 3D images to effect 3D display effect in a 3D display mode and to pass through light emitted from the display panel in a 2D display mode,wherein the light-splitting device includes;

    a first substrate having a plurality of first electrodes;

    a second substrate arranged facing the first substrate and having at least one second electrode;

    a liquid crystal layer placed between the first substrate and the second substrate and containing liquid crystal molecules; and

    a plurality of spacers placed between the first substrate and the second substrate and in the liquid crystal layer to support a thickness of the liquid crystal layer; and

    wherein the driving circuit module is configured to;

    when in the 3D display mode, provide a plurality of driving voltages between the first electrodes and the second electrode to make the liquid crystal layer an array of liquid crystal lenses; and

    when in the 2D display mode, provide a deflection voltage between the first electrodes and the second electrode to reduce a refractive index difference between the liquid crystal molecules and the spacers with a predetermined range.
