Abstract
A first liquid crystal cell of a plurality of liquid crystal cells of an optical element includes a first alignment film covering first and second transparent electrodes on a first substrate, a second alignment film covering third and fourth transparent electrodes on a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The first liquid crystal cell includes the first and second transparent electrodes extending in a first direction, the third and fourth transparent electrodes extending in a second direction, the first alignment film aligning liquid crystal molecules in the liquid crystal layer in the second direction when no voltages are applied to the first and second transparent electrodes, and the second alignment film aligning liquid crystal molecules in the liquid crystal layer in the second direction when no voltages are applied to the third and fourth transparent electrodes.
