Abstract
An electro-wetting apparatus includes a liquid having conductivity or polarity and a first electrode and a second electrode that apply voltage to the liquid. The electro-wetting apparatus also includes a dielectric layer provided between the liquid and the first electrode. The electro-wetting apparatus further includes a voltage-applying unit that applies a voltage signal between the first electrode and the second electrode, where the voltage signal is periodically changed between a first voltage of zero (0) volt or more and a second voltage of larger than the first voltage.
