The compensation principle to reduce the off‐axis light leakage of crossed polarizers is investigated. After optimizing the retardation films, the simulation results show that the black state of viewing angle of compensated TN and VA modes can be made wider than the angle of view of crossed polarizers. The results are also confirmed by the test cells.
