PURPOSE: An electrowetting display is provided to gradually adjusting the tones of each pixel by offsetting the effect of an interfacial tension with the insulation layer. CONSTITUTION: An insulating layer(113) is placed as a layer including an inclined surface in the front side of a first support substrate including a pixel electrode(112). A cladding layer(114) is placed on the insulation layer corresponded to the outside of a pixel opening unit. A pixel wall(115) placed on the insulation layer defines a pixel coping with a pixel boundary. A second support substrate(121) is arranged facing the first support substrate.
