Abstract
The present invention applies the voltage that is swung to the notch electrode of each pixel of the electrowetting display device to reset the oil layer to not backflow such that an additional element is not disposed in the pixel, thereby increasing the aperture ratio of the pixel. Also, the reset signal generator generating and applying the reset signal is disposed inside the electrowetting display device such that additional wiring may not be disposed in the outer part of the panel.
