Abstract
In a method for driving an optical element including a first liquid crystal cell, the first liquid crystal cell includes a first substrate on which first and second transparent electrodes are arranged in a first direction, a second substrate on which third and fourth transparent electrodes are arranged in a second direction, and a first liquid crystal layer between the first substrate and the second substrate, and the method includes the steps of inputting a first signal to the first transparent electrode, inputting a second signal having a phase difference of π with respect to the first signal to the second transparent electrode, inputting a third signal having a phase difference of α with respect to the first signal to the third transparent electrode, and inputting a fourth signal having a phase difference of π with respect to the third signal to the fourth transparent electrode.
