Abstract
Provided is an electrowetting device capable of performing bright and high-contrast color display. In addition, provided is an electrowetting device capable of performing high-quality display without unevenness. The electrowetting device is an electrowetting display in which each of a pair of substrate constituting one cell has a driving unit. A first substrate that stores a first hydrophobic liquid material in regions surrounded by a first pixel wall, and a second substrate that stores a second hydrophobic liquid material in regions surrounded by a second pixel wall are adhered to each other through a hydrophilic material.
