Abstract
An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include an electrode layer on the support plate, and a dielectric barrier layer on the electrode layer. The dielectric barrier layer comprises a first portion having a first dielectric constant and a second portion having a second dielectric constant that is substantially less than first dielectric constant. A hydrophobic layer is on the first portion and the second portion of the dielectric barrier layer.
