Title:
STEREOSCOPIC IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/042930
Kind Code:
A1
Abstract:
[Problem] To provide a stereoscopic image display device with which it is possible to enjoy the advantages of both eyeglasses format and naked-eye format devices while being capable of being reduced in size. [Solution] When a right-eye image is displayed, a light-block region BR1 is formed to the left of the center line, and when a left-eye image is displayed, a light-block region BR2 is formed to the right of the center line. When an observer is positioned in said position, the observer's right eye ER observes only the right-eye image, and the observer's left eye EL observes only the left-eye image. As a result, the observer is capable of observing a stereoscopic image in the position of the light-block regions BR1 and BR2 even when facing a stereoscopic display device (1) with the naked eye. Additionally, while a state will occur in a region other than the light-block regions BR1 and Br2 wherein the right-eye image and left-eye image are intermingled, it will be possible for a plurality of observers to simultaneously observe the same stereoscopic image by wearing eyeglasses for observing such images.
