The apparatus a display panel, a driving circuit part, a polarization switch panel and a lens. The driving circuit part processes received frame image data representing two-dimensional (2D) imagery and three-dimensional (3D) imagery to thus provide the display panel with the processed frame image. The polarization switch panel is disposed above the display panel. The polarization switch panel is switched into a first polarization mode in correspondence with 2D imagery being displayed by the display panel and it is switched into a second polarization mode in correspondence with 3D imagery being displayed by the display panel. The lens is reacts differently to light rays having the effect of the first polarization mode imparted to them and to light rays having the effect of the second polarization mode imparted to them.
