Abstract
A liquid crystal lens optical body that is available to a rapid response, the liquid crystal lens optical body having a first liquid crystal lens in which a liquid crystal layer is held between first electrodes, the first liquid crystal lens changing optical power by controlling orientation condition of liquid crystal molecules based on an input signal to the electrodes, and a second liquid crystal lens in which a liquid crystal layer is held between second electrodes, the second liquid crystal lens changing optical power by controlling orientation condition of liquid crystal molecules based on the input signal to the electrodes, the first and second liquid crystal lenses provided on an optical axis. In each liquid crystal lens, a response characteristic when the optical power undergoes a transition from a large condition thereof to a small condition thereof is different from a response characteristic when the optical power undergoes a transition from a small condition thereof to a large condition thereof.
