Liquid crystal optical apparatus and image display device having particular electrodes

摘要

According to one embodiment, a liquid crystal optical apparatus includes a first substrate unit, a second substrate unit, and a liquid crystal layer. The first substrate unit includes a first substrate and a plurality of first electrodes. The first electrodes are provided on the first substrate to extend in a first direction. Each of the first electrodes has a first side surface and a second side surface opposite to the first side surface. The second substrate unit includes a second substrate and an opposing electrode. The second substrate opposes the first substrate. The opposing electrode is provided on the second substrate to oppose the first electrodes. The liquid crystal layer is provided between the first substrate unit and the second substrate unit. The first side surface has a first protruding portion and a first recessed portion arranged with the first protruding portion in the first direction.
