LIQUID CRYSTAL OPTICAL COMPONENT, LIQUID CRYSTAL OPTICAL DEVICE AND METHOD FOR MANUFACTURING LIQUID CRYSTAL OPTICAL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal optical component and a liquid crystal optical device which are compact and have the small number of components and simple constitution, and a method for manufacturing the liquid crystal optical component.;SOLUTION: The liquid crystal optical component is provided with: a high molecular liquid crystal composite layer wherein liquid crystal particles are dispersed into macromolecules; a pair of electrodes formed in the high molecular liquid crystal composite layer so that the light transmittance of the high molecular liquid crystal composite layer is changed by applying a voltage to the high molecular liquid crystal composite layer; a light receiving part for receiving a part of light scattered in a portion where the light transmittance of the high molecular liquid crystal composite layer is changed due to the application of the voltage from the pair of electrodes out of light transmitted the high molecular liquid crystal composite layer; and a voltage control part for varying the level of voltage to be applied from the pair of electrodes to the high molecular liquid crystal composite layer on the basis of the light quantity of light received by the light receiving part.;COPYRIGHT: (C)2009,JPO&INPIT
