Abstract
The stereoscopic image display apparatus of this invention includes an upper light source unithaving a pair of light sourcesandand a lower light source unit, which are arranged between a reflection unitwith an elliptical mirrorhaving one focus fon the side of a reflecting surface, and a transmission type liquid crystal display panel. Thus, the apparatus has a reduced width. Moreover, the elliptical mirroris the stationary type, and the reflecting surfaceemployed is shaped symmetrical in plan view. This allows the respective light sources to use the common elliptical mirror. Therefore, the stereoscopic image display apparatus realizes a reduction in size and a reduction in apparatus cost.
