Title
(EN) OPTICAL MODULATION DEVICE
(FR) DISPOSITIF DE MODULATION OPTIQUE
(KO) 광변조 디바이스
Abstract
(EN) The present invention relates to an optical modulation device and a use thereof. The present invention may provide an optical modulation device which achieves low transmissivity in a blocking mode and has a wide transmittance-variable range, and does not cause problems such as liquid crystal defects or visibility degradation and the like. In addition, the present invention may provide a use of the optical modulation device.
(FR) La présente invention concerne un dispositif de modulation optique et son utilisation. La présente invention peut fournir un dispositif de modulation optique qui permet d'obtenir une faible transmissivité dans un mode de blocage et a une large plage de transmittance variable et ne provoque pas de problèmes tels que des défauts de cristaux liquides ou une dégradation de la visibilité et similaires. De plus, la présente invention peut concerner une utilisation du dispositif de modulation optique.
(KO) 본 출원은 광변조 디바이스 및 그 용도에 관한 것이다. 본 출원에서는 차단 모드에서 낮은 투과율을 구현하는 동시에 투과도 가변 범위가 넓고, 액정 결함이나 시인성 저하 등의 문제를 유발하지 않는 광변조 디바이스를 제공할 수 있다. 또한, 본 출원에서는 상기 광변조 디바이스의 용도를 제공할 수 있다.
