Abstract:
1. An electrowetting display device comprising: a first base substrate that includes a plurality of pixels; a second base substrate that faces the first base substrate and includes a common electrode; an electrowetting layer disposed between the first base substrate and the second base substrate; a plurality of pixel electrodes disposed on the first base substrate to respectively correspond to the pixels; a black matrix that includes a plurality of openings corresponding to respective ones of the pixels, the black matrix having a first extension portion extending in a driving direction of the electrowetting layer, the driving direction being a direction in which motion of the electrowetting layer is induced when a voltage difference is applied between the common electrode and the corresponding pixel electrode, and extending in a second direction substantially perpendicular to the driving direction; and a partition wall that partitions the pixels, wherein the first extension portion comprises a first area, a second area, and a third area, the first area and the second area respectively extending in opposite directions to each other, and wherein the third area has a width substantially the same as a width of the partition wall, the first area has a width less than about half of a first length corresponding to a length extending between both sides of each pixel in the driving direction of the electrowetting layer, and the second area has a width less than the width of the first area.
