Abstract:
Disclosed is an electrowetting device. The electrowetting device includes a conductive or polar liquid material, and an electrode applying voltage to the liquid material through a dielectric layer. In the electrowetting device, the dielectric layer is formed as an anodized portion made of a metal oxide formed by anodizing the electrode, and a voltage applying unit applying voltage between the electrode and the liquid material and a polar capacitor are placed between the electrode and the liquid material.
