Abstract
An electrowetting display comprises a first substrate and a second substrate. A plurality of first conductive electrodes is formed over the first substrate. A second conductive layer is formed over the second substrate and spaced apart from the plurality of the first conductive electrodes. A plurality of cells is formed over the first conductive electrodes. Each cell is formed between one of the first conductive electrodes and the second conductive layer. Each two adjacent cells being separated by a partition. At least two cells include a first material and a second material over the first material. The at least two cells have two different colors. A shape of the first material is capable of being changed upon a change of an electrical field between the first conductive electrode and the second conductive layer.
