An electrowetting display device includes a first base substrate, a second base substrate facing the first base substrate, an electrowetting layer that includes a first fluid and an electrically conducting second fluid that are immiscible with each other, black partition walls disposed on the first base substrate to partition a display area into pixel areas, and an electronic device that applies a voltage to the electrowetting layer to control the electrowetting layer. The partition walls restrict a flow of at least one of the first fluid or the second fluid.
