With the development of large‐scale displays, higher requirements are put forward for large view angle. Color shift of wide view at dark state is an important part of evaluating the quality of large size LCD panels. In this paper, the effects of the following four aspects are studied: liquid crystal orientation pretilt angle, liquid crystal alignment deviation angle, deviation angle of polarizer attached, polarizer's retardation. In this paper, the improvement measures are proposed.
