Abstract: 본 발명은 하이브리드 배향된 액정을 사용한 프린지 필드 스위칭(FFS: Fringe-Field Switching) 모드의 단일 패널을 이용한 시야각 조절 액정 표시 장치 대해 개시한다. 개시된 본 발명은 기존 FFS 모드의 전극구조에 상부기판에 상부 공통전극이 추가적으로 배치되어 있는 구조로, 하부기판의 액정들은 수평배열이고 상부기판의 액정들은 수직배열로 하이브리드 배향된 액정층으로 이루어져 있다. 하부 기판의 화소전극과 하부 공통전극에 의해 구동될 시에는 하이브리드 배열된 액정의 좁은 시야각 특성으로 인해 협시야각이 나타나고, 상부 공통전극과 하부 공통전극 사이의 발생한 수직 전기장에 의해 유전율 이방성이 음인 액정이 기판에 평행하게 누운 상태에서 하부기판에 위치한 화소전극과 하부 공통전극에 의해 구동 될 시에는 광시야각이 나타나게 되는 원리이다. 본 시야각 조절 액정 표시 장치는 단일 패널을 이용하였기 때문에 두께가 얇고, 경량이며, 개구율 감소 없이 시야각 조절이 가능하다는 것을 그 장점으로 한다.

Abstract: A single gap transflective liquid crystal display is provided to manufacture the single gap transflective liquid crystal display by making initial phase delay values of liquid crystal of a transmitting area and a reflecting area different, thereby removing complexity of the manufacture. A transparent electrode(3) of a conductive electrode type is coated on only a reflecting region of an upper glass substrate lower part. A common electrode(11) of the conductive electrode type is put on a transmitting area of the lower glass substrate upper part. The common electrode is coated only on the transmitting area. Also, the common electrode is coated on the reflecting area to control Cst as much as desired. The TFT can be placed in one of the reflecting area or a transmitting area because a pixel electrode and the reflecting electrode are directly connected.
