Abstract:
An optical low-pass filter is constituted with a liquid crystal substrate including a layer of liquid crystal. The optical low-pass filter includes: a first liquid crystal part in which the liquid crystal is aligned along a first direction; and a second liquid crystal part in which the liquid crystal is aligned along a second direction different from the first direction. The first liquid crystal part and the second liquid crystal part are disposed in an alternately repeated fashion.
