    • An electrophoretic display device has a first substrate that defines a plurality of sub-pixel areas; with shaped pixel electrodes formed in the sub-pixel areas. A second substrate is attached in facing relation to the first substrate during mass production. The second substrate has color filters of different colors (e.g., R, G, B). The areas of the color filters are less than the areas of their corresponding sub-pixel electrodes so as to thereby avoid or reduce a color mixture effect that may arise from mass production misalignment between the first and second substrates. In one class of embodiments, area consumed by the color filters is less than about 75% but more than about 45% of area consumed by respective pixel areas. Each pixel area comprises a white (W) sub-pixel area in addition to the differently colored sub-pixel areas (e.g., R, G, B).
    • 电泳显示装置具有限定多个子像素区域的第一基板; 具有形成在子像素区域中的成形像素电极。 在批量生产期间,第二衬底面向第一衬底附接。 第二基板具有不同颜色(例如,R,G,B)的滤色器。 滤色器的面积小于其对应的子像素电极的面积,从而避免或减少可能由第一和第二基板之间的批量生产不对准而引起的混色效果。 在一类实施例中,滤色器消耗的面积小于相应像素区域消耗的面积的约75%,但大于约45%。 每个像素区域除了不同颜色的子像素区域(例如,R,G,B)之外还包括白色(W)子像素区域。
