ABSTRACT:
The transparent electrode of the liquid crystal panel includes the first partial electrode portion constituted by the pattern electrodes and the second electron portion constituted by the pattern electrodes. When the central axis of the objective lens and the central axis of the liquid crystal panel are aligned with each other, the light beam passes through the first electrode portion. In this case, wavefront aberration is compensated by providing a predetermined phase difference to the light beam in the region of the liquid crystal corresponding to the first electrode portion. When the positions are not aligned and misalignment occurs, the light beam passes through the first electrode portion and the second electrode portion. In this case, wavefront aberration is compensated by providing a predetermined phase difference to the light beam in the region of the liquid crystal corresponding to the first electrode portion and the second electrode portion.
