<p>Provided is a lens array which can make characteristics of lens elements uniform. A lens array (10) is provided with a conductive first liquid (11); an insulating second liquid (12) having a refraction index different from that of the first liquid (11); and a plurality of lens elements (13) forming lens planes (13A) with interfaces between the first and the second liquids (11, 12). The lens plane (13A) of the lens element (13) reversibly changes by output control of an applying voltage. Since the adjacent lens elements (13) are communicated through the liquids, fluctuation of the liquid quantities of the first and the second liquids (11, 12) between the lens elements can be eliminated and the lens characteristics can be made uniform.</p> |
