An electrostatic driving device according to the present invention has a flexible thin film, a holding member, which holds the flexible thin film and allows the flexible thin film to bend, a function member disposed on the flexible thin film, a film-side facing electrode disposed on the flexible thin film, a base, which faces the holding member, a base-side facing electrode, which is disposed on the base and faces the film-side facing electrode; and a bonding spacer member, which is held between the holding member and base, bonds the holding member to the base, and holds an interval between the holding member and base at a predetermined interval so as to keep an electrode interval between the film-side facing electrode and base-side facing electrode at a predetermined interval.

Electrostatic driving device having an interval between electrodes facing each other and manufacturing method of the same

A liquid crystal lens comprises a biconcave lens and a pair of transparent flat plates arranged before and behind the lens. The biconcave lens has a pair of concave principal surfaces covered with transparent electrodes, a flat portion on its outer periphery, and an electrode extending across the flat portion and connecting the transparent electrodes. Each of the transparent flat plates has a flat principal surface covered with a transparent electrode, the surface facing the concave principal surface, a flat portion on its outer periphery, and an electrode extending across the flat portion and connected to the transparent electrode. The biconcave lens and the pair of transparent flat plates are cemented to one another in a spaced manner by sealants with their respective flat portions flush with one another. Liquid crystals are stored individually in spaces defined between the lens and the flat plates.
