Abstract
The present invention discloses an electrowetting display device and a method for preparing the same. The electrowetting display device comprises several fluid chambers and a polar fluid accommodated in the fluid chambers, wherein the fluid chamber comprises a base; the base comprises a first electrode and a second electrode that are insulated from each other and an electro-conversion film, wherein the electro-conversion film is located on one side of the first electrode that is adjacent to the polar fluid; and wherein the contact angle between the electro-conversion film and the polar fluid converts in the range from a first contact angle to a second contact angle according to the magnitude of a voltage applied; the first contact angle is no larger than 25 degrees, and the second contact angle is no less than 90 degrees.
