Abstract

According to one embodiment, a liquid crystal optical element includes: a pair of first and second substrates; a liquid crystal layer provided between the first and second substrates; first electrodes provided on the first substrate on the liquid crystal layer side and arranged along a first direction; second electrodes provided on the second substrate on the liquid crystal layer side and arranged along a second direction; and a driving unit configured to apply a voltage between the first electrodes and the second electrodes. The first electrodes are divided into electrode regions arranged along a third direction. The first electrodes included in each of the electrode regions are electrically connected to an extension line.
