Abstract

본 발명은 가변 광 위상차 보상 필름에 관한 것으로서 폴리머 분산 액정을 이용한 가변 광 위상차 보상 필름에 관한 것이다. 본 발명은 폴리머에 액정 방울이 분산되어 있는 광제어층을 갖추며, 상기 액정은 어느 일방을 향하여 배향처리되어 있고, 상기 광제어층의 양측에는 상기 액정의 배향정도를 보정하여 능동적으로 광위상차를 보상하는 전극이 마련되어 있다. 이러한 본 발명은 액정 표시 소자의 광 위상차 보상용으로 적용될 수 있는데, 액정 표시 소자의 광제어 특성에 부착되는 같은 특성의 액정을 사용할 수 있고 특히 복굴절율의 임의 조정이 가능하므로 효과적인 광 위상차 보정이 가능하다.The present invention relates to a variable light retardation compensation film and a variable light retardation compensation film using a polymer dispersed liquid crystal. The present invention includes a light control layer in which liquid crystal droplets are dispersed in a polymer, and the liquid crystal is aligned in one direction, and both sides of the light control layer actively compensate for the optical phase difference by correcting the degree of alignment of the liquid crystal. An electrode is provided. The present invention can be applied for the compensation of the optical phase difference of the liquid crystal display device, and the liquid crystal having the same property attached to the light control property of the liquid crystal display device can be used, and in particular, since the arbitrary adjustment of the birefringence can be performed, the effective optical phase difference correction is possible. Do.
