Title:
ILLUMINATING DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE AND IMAGE DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/066778
Kind Code:
A1
Abstract:
The present invention pertains to an illuminating device (2) used in a liquid crystal display device (100) that alternately focuses light on a right eye (17a) position and a left eye (17b) position of a viewer (16). The illuminating device (2) is provided with a planar illuminating body (6) that focuses emitted light on prescribed focal points, and a light deflector (7) that two-dimensionally deflects light from the planar illuminating body (6). By switching the direction of the light that is emitted, the planar illuminating body (6) can alternately switch between a first light-focusing state in which the prescribed focal point is positioned at the right eye (17a) of the viewer (16), and a second light-focusing state in which the prescribed focal point is positioned on the left eye (17b) of the viewer (16). The light deflector (7) is able to track the motion of the viewer (16), and adjust the prescribed focal point in the first light-focusing state and the prescribed focal point in the second light-focusing state.
