摘要： The present invention relates to a transparent liquid crystal display device. The transparent liquid crystal display device may clearly form an image from a liquid crystal display device while clearly discriminating an object or an image located at an opposite side. A characteristic of the present invention is to form a liquid crystal layer of the transparent liquid crystal display device in a guest host mode in which a dichroic black dye is mixed and a O-mode; form first and second electrodes capable of forming a fringe field on a first substrate; further form a third electrode on a second substrate to form a vertical electric field through the first and third electrodes; and form dichroic color filters of red (R), green (G), and blue (B) using dichroic color dyes with specific polarization axis, so that light is selectively transmitted or blocked to implement a transparent state, a color state, and a black state. Accordingly, the transparent liquid crystal display device of the present invention may clearly form an image from the liquid crystal display device while clearly discriminating the object or the image located at the opposite side.

CONSTITUTION: A design method of a 2D-3D switchable LC lens comprises an LC layer and film layers. In the LC layer, an LC arrangement direction can be changed by voltage.

摘要： 본 발명은 액정표시장치에서 시야각 보상필름을 사용하여 측면 시야각을 개선시키는 광시야각형 수직정렬 액정셀을 위한 광학구조를 구성함에 있어서, 뽀앙카레 구에서 광시야각을 얻을 수 있도록 두개의 A-플레이트와 두개의 C-플레이트를 적용하므로써, 측면 시야각에서의 명암대비비(contrast ratio) 향상뿐만 아니라 어두운 상태일 때의 가시광의 범위 내에서 색의 분산특성을 제거할 수 있도록 하는 광시야각형 수직정렬 액정셀을 위한 광학구조를 제공한다. 이에 따르면, 광학구조를 통과한 가시광 범위 내 빛의 모든 편광상태가 뽀앙카레 구면 상의 상측 편광판 흡수축을 나타내는 편광지점으로 이동하기 때문에 어두운 상태에서 측면 시야각 빛 샘 현상이 제거되므로, 수직정렬 액정표시장치에서 시야각에 따른 위상차 값을 광학적으로 보상함으로써 측면 시야각에서도 정면 시야각 수준의 우수한 광학특성을 얻을 수 있다.

摘要： An LCD(Liquid Crystal Display) is provided to enhance not only the contrast ratio and but also to have the wide viewing angle by means of a phase shift film and a C-plate. A liquid crystal cell(130) controls the transmittance of the external light beam by applying voltage. A side of biaxial compensating film(210) is attached at a side of the liquid crystal cell so that the viewing angle is compensated. A C-plate(220) is attached at the other side of the liquid crystal cell so that the transmittance of the liquid crystal cell according to the viewing angle is compensated. A reflection plate(140) is attached at least a portion of a side of the C-plate and reflects the external light beam. A polarizing film is attached at the other side of the biaxial compensating film. The delay value of the liquid crystal layer used to the liquid crystal is 1/4 of the wavelength of the external light. The biaxial compensating film converts the wavelength of the external light into 1/2 wavelength.
