PROBLEM TO BE SOLVED: To provide an optical element capable of achieving accurate driving at a low voltage while maintaining sufficient insulating property.SOLUTION: The optical element includes: first and second substrates disposed to oppose to each other; a pair of walls formed on an inner surface of the first substrate, the inner surface opposing to the second substrate, standing to adjoin to each other in a first direction and extending in a second direction; first and second electrodes formed on wall surfaces of the pair of walls, insulated from and opposing to each other as well as separated from the first substrate, and each extending in the second direction; first and second terminals connected to both ends of the first electrode; third and fourth terminals connected to both ends of the second electrode; an insulating film covering each of the first and second electrodes; a third electrode disposed on an inner surface of the second substrate, the inner surface opposing to the first substrate; and a polar liquid and a non-polar liquid having refractive indices different from each other. |
