Abstract: 본 발명은 단일갭 또는 이중갭 구조의 반투과형 액정 표시 장치의 제조 공정에 관한 것이다. 본 발명은 단일갭 또는 이중갭을 갖는 반투과형 액정 표시 장치에서 컬러 필터 층과 차광 부재 등을 포함하는 상부 표시판의 제조 방법에 관한 것이며 이는 공정 단순화와 액정 표시 장치의 동작에 있어서 안정화를 가진다.
이는 기존의 반투과형 액정 표시 장치의 상부 표시판 제조시, 상부 유리 절연 기판 위에 차광 부재를 두고 상기 차광 부재 위에 컬러 필터 수지를 코팅하고 반사부의 광 효율 증가를 위해 컬러 필터의 일부분에 구멍을 형성시킨 후, 상기 컬러 필터 위에 내장형 위상자를 코팅하고 상기 내장형 위상자 위에 배향막을 두는 방식의 제조 방식을 사용하였다. 그러는 상기의 방법은 컬러 필터에 존재하는 투과영역의 작은 원형의 홀 때문에 균일한 셀갭을 유지하기가 어렵고 이는 액정 분자의 움직임과 광학 특성을 저해하는 요소가 된다. 또한 이는 제조 공정을 증가시키며 제조 원가를 높이기도 한다.
본 발명에 의하면 반투과형 액정 표시 장치의 상부 표시판 제조시, 상부 유리 절연 기판 위에 위상지연의 기능을 가지는 내장형 위상자를 코팅하고 상기 내장형 위상자 위에 차광 부재를 두고 상기 차광 부재 위에 컬러 필터 수지를 평탄화 코팅을 하는 것이다. 본 발명에 따른 반투과형 액정 표시 장치의 상부 표시판의 제조 방법에 의하면 상기에 설명한 기존의 반투과형 액정 표시 장치의 상부 표시판에 비하여 균일한 셀갭을 얻을 수 있고 이에 따라 안정한 액정 분자의 움직임과 광학 특성의 균일함을 보여주며 제조 공정 또한 단순화되는 특징이 있다.
이는 투과영역과 반사영역의 셀갭이 동일하거나 다르게 제작된 액정 표시 장치 모두에 적용 가능하며, 제조 공정 단순화 및 동작 효용을 높일 수 있다는 장점이 있다.

Abstract: An LCD(Liquid Crystal Display) having a linear pillar spacer is provided to prevent liquid crystal from being inclined in the direction of gravity and to uniformly maintain cell gaps by locating a linear pillar spacer at a portion where a black matrix exists. On a glass substrate, a black matrix(12) is formed to intercept an unnecessary light leakage region and to classify RGB resins. RGB resins are selectively formed on the substrate where the black matrix(12) are formed. Then a protection film is formed on the whole substrate where the RGB resins and the black matrix(12) are formed. A common electrode is coated to inject voltage on the protection film. A photosensitive resin layer is formed on the common electrode. A dotted line-shaped linear pillar spacer(16) is formed through the developing of the photosensitive resin layer.
