Abstract
A liquid crystal lens device includes first electrodes, first and second sub electrodes, an opposite electrode, and a liquid crystal layer. The first electrodes extend in a first direction and are arranged in a second direction crossing the first direction. The first sub electrode is provided between a center in the second direction of two nearest ones of the first electrodes and one of the two nearest first electrodes. The second sub electrode is provided between the center and the other of the two nearest first electrodes. The opposite electrode is opposed to each of the first electrodes, the first sub electrode, and the second sub electrode. The liquid crystal layer is provided between the first electrodes and the opposite electrode, between the first sub electrode and the opposite electrode, and between the second sub electrode and the opposite electrode.
