Abstract
The disclosure provides an electrowetting display device. The electrowetting display device includes a first substrate and a second substrate disposed to each other. A first electrode layer may dispose on the first substrate. A second electrode layer may dispose on the second substrate. A hydrophobic dielectric layer is disposed on the first electrode layer. A first pixel rib is disposed on the first substrate. A second pixel rib is disposed on the first pixel rib. A water contact angle of the second pixel rib may be larger than that of the first pixel rib. A first liquid and a second liquid may be disposed in between the first substrate and the second substrate.
