Abstract
A stereoscopic image display apparatus having a light source that defines at least one right and left light-cells which provide plural pairs of right and left lights. A spatial modulator, spaced apart from the light source, spatially modulates the right and left lights from the light source so as to focus the right and left lights on the eyes of at least one viewer. A display mode changer is capable of automatically changing the display mode of the image display between a stereoscopic image display mode and a normal plane image display mode. The display is automatically changed in accordance with the location of the viewer or in response to an instruction from the viewer.
