By setting the linearly polarized light with normal incidence on the liquid crystal sample 3 and rotating the liquid crystal sample 3 on a rotation stage 7 within plane, the dependencies of the amplitude ratio as well as the optical retardation of the transmitted light on the azimuth of the liquid crystal sample, with respect to the polarization direction of the incident light, are measured. From these measured results, a liquid crystal pretilt angle is determined.
