Document Type and Number:
Japanese Patent JP4878065
Kind Code:
B2
Abstract:
The stereoscopic image display apparatus of this invention includes an upper light source unit 29 having a pair of light sources 33 and 35 and a lower light source unit, which are arranged between a reflection unit 17 with an elliptical mirror 15 having one focus fl on the side of a reflecting surface 19, and a transmission type liquid crystal display panel 5. Thus, the apparatus has a reduced width. Moreover, the elliptical mirror 15 is the stationary type, and the reflecting surface 19 employed is shaped symmetrical in plan view. This allows the respective light sources to use the common elliptical mirror 15. Therefore, the stereoscopic image display apparatus realizes a reduction in size and a reduction in apparatus cost.
