摘要

We investigated the optical phase compensation of uniaxial layers and found a thickness ratio that gives the perfect phase compensation. However, the ratio is a function of the incident light angle and director configuration. Therefore, it is impossible to compensate the phase of a generally configured uniaxial layer perfectly for all viewing directions. We also found that the efficiency of the phase compensation is a strong function of the residual birefringence and the director tilt angle of a liquid crystal layer. We confirmed these facts for both the uniformly and non-uniformly aligned liquid crystal layers.
