Title:
LIQUID CRYSTAL SHUTTER AND LIQUID CRYSTAL SHUTTER EYE GLASSES
Document Type and Number:
WIPO Patent Application WO/2010/098341
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal shutter having two superimposed liquid crystal layers in which no leakage of light occurs. In a liquid crystal shutter in which oriented films (11) of a pair of substrates of each liquid crystal device (8a, 8b) are oriented in mutually intersecting directions, and are all vertically oriented films or horizontally oriented films, and if the oriented films are horizontally oriented films, the liquid crystal materials have a positive dielectric constant isotropy, and if the oriented films are vertically oriented films, the liquid crystal materials have a negative dielectric constant isotropy, the twist directions (13) of the liquid crystal materials enclosed in the adjacent liquid crystal devices (8a, 8b) are opposite to each other to thereby prevent the leakage of light.
