    • A color display device comprising at least two substrates spaced from each other, the substrates each having an internal and an external surface, the internal surfaces of the two substrates facing each other, at least one of the substrates being transparent; electrodes positioned to establish a field in the space between the two substrates; an optically active material occupying at least a portion of the space between the two substrates and having optical properties influenced by the field; a color filter layer comprising color filter elements that alter the color of light traveling through the color filter layer, the color filter elements being positioned outside of the space between the two substrates; and a three-dimensional black mask comprising mask elements aligned with the boundaries between adjoining color filter elements. The three-dimensional black mask structure allows the color filter to be placed on the exterior of the display while still maintaining good color performance under off-axis viewing conditions.
    • 一种彩色显示装置,包括彼此间隔开的至少两个基板,所述基板各自具有内表面和外表面,所述两个基板的内表面彼此面对,所述基板中的至少一个是透明的; 定位以在两个基板之间的空间中建立场的电极; 占据两个基板之间的空间的至少一部分并具有受该场影响的光学特性的光学活性材料; 滤色器层,其包括改变穿过滤色器层的光的颜色的滤色器元件,滤色器元件位于两个基板之间的空间的外侧; 以及包括与邻接的滤色器元件之间的边界对准的掩模元件的三维黑色掩模。 三维黑色掩模结构允许将滤色器放置在显示器的外部,同时在离轴观察条件下仍保持良好的色彩性能。
