Abstract
An electrowetting display device includes a first support plate and a second support plate opposite the first support plate, and a plurality of pixel walls over the first support plate. The plurality of pixel walls are associated with an electrowetting pixel and define a volume containing at least a portion of an oil and an electrolyte fluid. The electrolyte fluid has a first refractive index. The electrowetting display device includes a pixel spacer between a first pixel wall in the plurality of pixel walls and the second support plate. A second refractive index of the pixel spacer is less than the first refractive index. The electrowetting display device includes a pixel electrode over the first support plate for applying a voltage within the electrowetting pixel to cause relative displacement of the oil and the electrolyte fluid.
