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 40 according to the present invention, a plurality of pyramidal recesses 48 that receive droplets 52 are two-dimensionally formed in a sealed cell 50 in which first liquid 51 that is conductive and second liquid (droplet) 52 that is insulative are contained without being mixed with each other. Since the recesses 48 are formed in a pyramidal shape, the centering performance of the droplets 52 placed in the recesses can be improved and variation in optical axes of lens elements formed of interfaces 53 of the droplets 52 can be suppressed. In addition, the optical axes can be stably positioned and decentering of the droplets 52 in the voltage-driven state can be suppressed. Furthermore, micro fabrication can be facilitated compared to the case in which the recesses 48 are conical, and the recesses can be densely arranged. |
