Abstract

본 발명은 액정라이트밸브 장치를 개시한다.The present invention discloses a liquid crystal light valve device.

본 발명은 액정과 이를 일측방향으로 배향시키기 위한 전극을 가진 액정라이트밸브와, 고전위전계에 의해 전자빔을 형성하여 소정의 화상을 실현하도록 된 냉음극전계방사표시패널이 형광막과 공통전극이 상기 액정라이트밸브의 관도전층에 형성된 것에 특징이 있으며, 이는 액정라이트밸브 장치의 구조를 간단하게 할 수 있고 광이용효율을 극대화 할 수 있는 이점이 있다.The present invention provides a liquid crystal light valve having a liquid crystal and an electrode for aligning it in one direction, and a cold cathode electroluminescent display panel configured to form an electron beam by a high potential electric field to realize a predetermined image. It is characterized in that formed in the conductive layer of the liquid crystal light valve, which can simplify the structure of the liquid crystal light valve device and has the advantage of maximizing the light utilization efficiency.
