An electrowetting display device includes a first base substrate, a partition wall which is on the first base substrate and partitions pixels, a second base substrate which faces the first base substrate, column spacers which are on the second base substrate and contact the partition wall, an electrowetting layer which is between the first and second base substrates and includes a first fluid and a second fluid immiscible with each other, and channels disposed in a boundary area between the pixels. The second fluid has electrical conductivity or electrical polarity. The boundary area is overlapped with the partition wall and the channels define a flow path of the second fluid. The column spacers are in the boundary area between the pixels except for a boundary area including the channels.
