Abstract: PURPOSE: A method for forming a metal line is provided to be capable of applying a damascene process and preventing an erosion phenomenon. CONSTITUTION: A structure(32) having a plurality of recess portions(32a) is formed on a substrate(30). A spacer layer(36) is formed at both sidewalls of each recess portion. A tungsten layer is formed on the entire surface of the resultant structure for completely filling the recess portions. At this time, the spacer layer has a polishing selectivity ratio larger than that of the tungsten layer as much as at least 50 times. A polishing process is performed on the tungsten layer until the upper surface of the structure is exposed. Preferably, at least two recess portions are formed on the structure and have different line widths. Preferably, the recess portion is contact hole or via hole. Preferably, the structure is made of an oxide layer.

Abstract: 컬러 필터 기판의 공통 전극 위에 화소 영역의 가운데에서 꺾어진 톱니 모양의 돌기를 형성하고, 박막 트랜지스터 기판의 화소 전극 위에 컬러 필터 기판 위의 돌기와 평행하게 교대로 톱니 모양의 돌기를 형성한다. 두 전극 위에는 톱니 모양 돌기의 꺾인 부분으로부터 반대쪽 기판 위의 돌기를 향하는 방향으로 가지 돌기를 형성하고, 공통 전극 위에 화소 전극의 경계와 박막 트랜지스터 기판의 돌기가 만나는 부분에서 화소 전극의 경계 쪽으로 연장되는 가지 돌기를 형성한다. 이렇게 하면, 전계가 인가되었을 때 하나의 화소 내에서 액정 분자의 배향 방향이 서로 다른 네 개의 영역을 얻을 수 있어 넓은 시야각을 확보할 수 있고, 대부분의 영역에서 돌기는 직선으로 형성되고 돌기가 꺾이는 부분에서도 둔각을 이루게 되어 빠른 응답 속도를 가지면서 액정 분자의 배향이 흐트러지는 경우에 발생하는 전경(disclination)을 없앨 수 있어 액정 표시 장치의 휘도를 향상시킬 수 있다.
