A lens array is provided. A manufacturing process is facilitated and micro fabrication can be performed. In addition, variation in an optical axis that depends on the processing accuracy and decentering of a droplet in the voltage-driven state is suppressed. In a lens array, a plurality of pyramidal recesses that receive droplets are two-dimensionally formed in a sealed cell in which first liquid that is conductive and second liquid (droplet) that is insulative are contained without being mixed with each other. Since the recesses are formed in a pyramidal shape, the centering performance of the droplets placed in the recesses can be improved and variation in optical axes of lens elements formed of interfaces of the droplets can be suppressed. In addition, the optical axes can be stably positioned and decentering of the droplets in the voltage-driven state can be suppressed. Furthermore, micro fabrication can be facilitated compared to the case in which the recesses are conical, and the recesses can be densely arranged. |
