Abstract: An electrowetting display apparatus includes a first substrate including a first electrode that receives a gray-scale voltage and a second electrode insulated from the first electrode and receiving a reference voltage, a second substrate, a fluid layer, and a color filter. The color filter has a first thickness in an area corresponding to the first electrode and a second thickness in an area corresponding to the second electrode, and the first thickness is larger than the second thickness. Accordingly, a cell gap of the electrowetting display apparatus is reduced, and color reproducibility of the electrowetting display apparatus is improved without sacrificing brightness.

Abstract: An electrowetting element includes a surface having a display area; a first fluid and a second fluid immiscible with the first fluid; and a non-switchable color filter for further determining the display effect. A configuration of the first and second fluids is switchable, using an applied voltage, to determine a size of area that the first and second fluids adjoin the display area, which thereby determines a display effect provided by the electrowetting element. An extent of the non-switchable color filter in a plane parallel to a plane of the display area is smaller than the display area.
