Claim Text:
1. A microlens array film comprising: a first transparent electrode and a second transparent electrode facing each other, at least one of the first and second transparent electrodes including a flat portion; a flexible polymer layer having a surface for forming lenses, the flexible polymer layer being placed between the first and the second transparent electrodes; a first substrate being in contact with at least a bottom surface of the flexible polymer layer, each of the first and second transparent electrodes being in direct contact with the first substrate; and a second substrate being flexible and in contact with at least a top surface of the flexible polymer layer, each of the first and second transparent electrodes being in direct contact with the second substrate, wherein a distance between the first transparent electrode and the second transparent electrode is reduced by applying voltages of opposite signs to the first and second transparent electrodes, respectively, wherein the surface for forming lenses changes as result of when the distance between the first transparent electrode and the second transparent electrode is reduced.
