Abstract
An electrowetting display apparatus includes a first base substrate, a second base substrate which faces the first base substrate, a first electrode on the first base substrate, and a second electrode on the second base substrate, where the second electrode faces the first electrode. A barrier wall is on the first electrode, where the barrier wall defines a storage area. A surface of the first electrode and the barrier wall is overlapped by a barrier layer. In addition, a water-repellent layer is on the barrier layer which is in the storage area. First and second fluids are in the storage area, the first fluid is separate from the second fluid, and the first fluid or the second fluid has a polarity.
