Abstract: A liquid crystal lens is formed with a first electrode formed on a first substrate and two or more second electrodes formed on a second substrate in a stripe pattern. Different voltages are applied to the second electrodes. The plurality of second electrodes exist at the boundary between a first liquid crystal lens and a second liquid crystal lens, and accept the maximum voltage of the different voltages. As a result, the liquid crystal lens can be moved in accordance with the movement of the visual line, the first and second liquid crystal lenses can be separated, and also a refractive index distribution of the liquid crystal lens can be close to a quadratic curve, thereby enabling to prevent the crosstalk.
