본 발명은, 시야각을 제어할 수 있는 차량 디스플레이용 광학계 및 이를 포함하는 차량용 디스플레이 장치로서, 차량에 설치된 디스플레이 패널의 좌측 시야각 또는 우측 시야각 중 선택된 하나의 측면 시야각을 차단할 수 있도록, 외부 전계를 통해 재배열될 수 있는 꼬임 액정층을 포함하는 전기-광학층; 상기 전기-광학층 상에 적층되고, 상기 하나의 측면 시야각에서의 빛 샘을 방지하는 광학 보상층; 및 상기 광학 보상층 상에 적층되고, 상기 디스플레이 패널의 제 1 편광층의 제 1 흡수축과 직교하는 제 2 흡수축을 갖는 제 2 편광층;을 포함할 수 있다.
The present invention relates to an optical system for vehicle displays, capable of controlling a viewing angle, and a display device for vehicles, comprising same, and may comprise, in order to block a side viewing angle selected from a left viewing angle or a right viewing angle of a display panel installed in a vehicle: an electro-optical layer comprising a twisted liquid crystal layer that can be rearranged through an external electric field; an optical compensation layer which is stacked on the electro-optical layer and prevents light leakage at the one side viewing angle; and a second polarization layer stacked on the optical compensation layer and having a second absorption axis orthogonal to a first absorption axis of a first polarization layer of the display panel.
