Abstract
A three-dimensional image display unit comprising a liquid crystal parallax barrier provided on the surface of an image display unit such as a transmitting liquid crystal display unit across a transparent plate, wherein a shielding member such as a black mask for shielding the outgoing light of a light incident from the side surface of the transparent plate is provided in the vicinity of the boundary of the effective display area of the parallax barrier. The shielding member may be provided inside or outside the parallax barrier. Such a construction can prevent blur forming in the vicinity of the boundary of the effective display area or a deterioration in display quality such as insufficient black displaying at a part that should be black-displayed, thereby providing a three-dimensional image display unit giving a good display quality in the vicinity of the boundary of the effective display area even if it is enlarged in size.
