Abstract

A lens array device and an image display device using the lens array device, which allow a lens effect characteristic different from that of a single variable lens array to be easily obtained, are provided. The lens array device includes a variable lens array and a fixed lens array. The variable lens array includes a plurality of variable lenses each having electrically-adjustable refracting power. The fixed lens array includes a plurality of fixed lenses each provided in correspondence to each of the plurality of variable lenses. Each of the fixed lenses has a refracting power which, once a corresponding variable lens has come to have a first refracting power, allows the first refracting power to be cancelled out.
