Abstract

본 발명은 호메오트로픽 배향되는 네마틱 액정에 전계를 가했을 때 액정이 수평배향되면서 선회성을 갖는 트위스트 네마틱 모드의 액정표시장치를 제공한다.The present invention provides a liquid crystal display device in twisted nematic mode that has liquid crystals in a horizontal orientation when the electric field is applied to the homeotropic oriented nematic liquid crystal.

본 발명의 액정표시장치는 콘트라스트비, 액전배향의 안정성, 시야각을 향상시키고, 문턱전압을 저하시켜 액정화면의 화질을 개선할 수 있다.The liquid crystal display device of the present invention can improve the contrast ratio, stability of liquid crystal alignment, viewing angle, and lower the threshold voltage to improve the image quality of the LCD screen.

Description
