PURPOSE: An array substrate for an in-plane switching mode liquid crystal display and a method for manufacturing the same are provided to improve an aperture ratio by widening an interval between a common electrode and a pixel electrode, minimize color shift, and widen an area having no gray scale inversion, thereby realizing an in-plane switching mode liquid crystal display having a wide view angle. CONSTITUTION: Gate lines(112) and data lines(124) vertically cross each other on a substrate for defining a pixel area(P). A thin film transistor is formed at a point where the gate lines and the data lines cross each other. A pixel electrode(130) is made up of a first horizontal part(130a) extended in one direction following a storage line on the storage line, a first vertical part(130b) and a second vertical part(130c) vertically extended from the first horizontal part to both sides of the pixel area, and a plurality of second horizontal parts(130d) formed in zigzags for connecting the first vertical part and the second vertical part. A common electrode(117) is formed in zigzags, parallel separated from the pixel electrode at a certain interval. 본 발명은 액정표시장치에 관한 것으로 특히, 횡전계 방식 액정표시장치에 관한 것이다. 본 발명을 요약하면, 화소영역에 동일 층으로 구성되는 공통전극과 화소전극을 가로방향으로 지그재그 형상으로 구성한다. 이와 같이 하면, 세로 방향으로 전극을 구성하는 것보다 전극간의 간격을 자유롭게 설계하는 것이 가능하고, 컬러 시프트 현상을 최소화하고 계조 반전이 없는 영역을 넓힐 수 있다. 따라서, 광시야각을 가지는 횡전계 방식 액정표시장치를 제작할 수 있다.
