Abstract
Embodiments of the invention provide an image display device that is switchable between a two-dimensional display mode, a three-dimensional display mode enabling non-autostereoscopic image display, and a three-dimensional display mode enabling autostereoscopic image display. In one embodiment, the image display device comprises a display panel operable to transmit light corresponding to image data; a polarization state conversion section comprising a first polarization segment for converting light transmitted by the display device to a first polarization state, and a second polarization segment for converting light transmitted by the display device to a second polarization state; and an optical separation element that is placed, via application of a voltage, in an on state in which light transmitted by the display panel is refracted or an off state in which light transmitted by the display panel is not refracted.
