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, a dielectric barrier layer on the electrode layer, a hydrophobic layer on the dielectric barrier layer, and quantum dots between the hydrophobic layer and the electrode layer. The quantum dots may utilize blue or white light illuminating the pixels to emit longer-wavelength colors such as red and green. Such a feature may enhance or replace functionality of color filters.

An electrowetting element comprises a first fluid and a second fluid immiscible with the first fluid. A first support plate comprises a first substrate; an electrode; and a layer in contact with at least one of the first fluid or the second fluid. A second support plate comprises a second substrate. One of the first support plate or the second support plate comprises a resist structure protruding in a direction towards the other one of the first support plate or the second support plate. The resist structure comprises a polymer nanocomposite material.
