Abstract
In a liquid crystal optical element, a first substrate includes a first main surface. A second substrate includes a second main surface opposed to the first main surface. First electrodes are provided on the first main surface. Common electrodes are provided on the second main surface. A liquid crystal layer is formed between the first main surface and the second main surface. A first alignment layer is formed between the first substrate and the liquid crystal layer. A second alignment layer is formed between the second substrate and the liquid crystal layer. The first alignment layer has an anchoring force that is weaker than an anchoring force of the second alignment layer.
