Abstract

본 발명은 시야각을 넓게 형성할 수 있는 액정표시소자 제조방법에 관한 것으로, 종래에는 액정표시소자의 시야각방향에서 좌우로 불균일한 콘트라스트가 발생하였으나, 본 발명에서는 상,하부 배향막(12,11)의 러빙방향 대칭축을 수평축으로 하지 않고 수평축에서 10°~ 30°이동하므로써 액정표시소자의 시야각이 좌우로 균일하며 넓어지므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a method for manufacturing a liquid crystal display device having a wide viewing angle. In the related art, non-uniform contrast occurs in the viewing angle direction of the liquid crystal display device. However, in the present invention, the upper and lower alignment layers 12 and 11 Since the viewing angle of the liquid crystal display device is uniform and wider to the left and right by moving the horizontal axis from 10 ° to 30 ° without the symmetry axis in the rubbing direction, the above-mentioned defect can be improved.
