Title:
THREE-DIMENSIONAL IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/048854
Kind Code:
A1
Abstract:
The advantages of both an eyeglass-type device and a glassless-type device can be received without switching or the like. Since a first display unit (7) and a second display unit (11) form light-shielded regions (BR2, BR1) on the right and left sides of the center line because of asymmetrical arrangement of light sources, an image observed with the right eye (ER) of an observer, who is at this position, is only an image for the right eye, and an image observed with the left eye (EL) of the observer is only an image for the left eye. As a result of this, at the position of the light-shielded regions (BR2, BR1), the observer can observe a three-dimensional image even if facing the three-dimensional image display device (1) without eyeglasses. Meanwhile, in regions except the light-shielded regions (BR2, BR1), the image for the right eye and the image for the left eye are in a mixed but differently polarized state, so that a plurality of observers, who respectively wear eyeglasses with differently polarized right and left glasses, can observe the same three-dimensional image simultaneously.
