An electrowetting display device includes a first support plate and a second support plate opposite the first support plate. A plurality of pixel walls are formed over the first support plate. The plurality of pixel walls are associated with a first pixel and a second pixel. The plurality of pixel walls define a first display area of the first pixel and a second display area of the second pixel. A first electrode is formed over the first support plate underneath the first display area of the first pixel. A second electrode is formed over the first support plate underneath the second display area of the second pixel. The first electrode is electrically connected to the second electrode. A first switch may be positioned underneath the second display area, with the first switch being electrically connected to the first electrode.
