Abstract
According to one embodiment, an image display device includes a liquid crystal optical device and an image displayer. The liquid crystal optical device includes a plurality of first electrodes, a plurality of second electrodes, a liquid crystal layer provided between the first and second electrodes, and a first driver. The first driver forms a refractive index distribution in the liquid crystal layer. The image displayer includes a plurality of subpixels. Each of subpixels has a first length along a third direction and a second length along a fourth direction. A distance along the third direction between most proximal electrodes of the first electrodes is shorter than a distance along the fourth direction between most proximal electrodes of the second electrodes.
