Abstract: A single gap transflective fringe field switching display is provided to facilitate release of static electricity by forming a polymer resin of an uneven shape only on a reflective area of a lower substrate and forming a reflective electrode of an uneven shape through the patterning of the reflective electrode on the polymer resin. An upper substrate is placed under an upper polarization panel(1). A common electrode(3) having a plane shape is placed under the upper substrate and includes a transmissive electrode placed at a lower side. An insulating layer is placed between the common electrode and a pixel electrode. The pixel electrode(5), which is a transparent electrode having a lattice shape, has a width ranging from 1 to 4 mum under the insulating layer, and an interval between the pixel electrode parts ranging from 1 to 6 mum. A liquid crystal layer(6) is arranged horizontally under the upper pixel electrode. A QWP(Quarter Wave Plate) is placed under a lower substrate. A lower polarizer panel(14) is under the QWP. A built-in phase shifter(7) is placed under the horizontally arranged liquid crystal layer. A color filter layer(9) is placed under the built-in phase shifter. A polymer resin layer(11) has an uneven shape, and is placed on the lower substrate of a reflective area. A reflective electrode(10) has an uneven structure and is placedon the polymer resin layer of the reflective area.

Abstract: 본 발명은 전기적인 스위칭 동작에 의해 광시야각에서 협시야각으로 시야각을 제어할 수 있는 액정표시소자에 관한 것으로, 구체적으로 소정화상을 표현하는 트위스트 네마틱(Twist nematic) 액정 층과 스위칭에 따라 시야각 조정 역할을 하는 수평배향(Homogeneous Alignment) 액정층이 한 개 또는 두 개로 구성되어있다. 이러한 액정표시장치의 수평배향 액정층에 전압을 인가하면 전압의 크기에 따라 액정층의 선경사각이 조절된다. 액정 분자의 선경사각이 커질수록 시야각에 따른 액정셀의 위상지연 값이 증가하기 때문에 시야각은 좁아진다. 결국 수평배향 액정층에 전압의 차이에 의해서 협시야각 또는 광시야각을 적절히 조절할 수 있다.
