To provide an electro-wetting apparatus which is operated at a low voltage in a wider variable voltage range, various apparatuses furnished with the electro-wetting apparatus and a method of driving the electro-wetting apparatus.

The electro-wetting apparatus includes: a liquid having electric conductivity or polarity; first and second electrodes for applying voltage on the liquid; a dielectric material layer provided between the liquid and the first electrode; and a voltage applying part. The voltage applying part applies a cyclicly varying voltage signal between a first voltage not smaller than 0 volt and a second voltage larger than the first voltage, namely, an alternating voltage which varies in a positive voltage range, upon the first and the second electrodes.
