摘要： Reflective electrodes having unevenness are formed on a resin layer of a TFT substrate. A coating-type ITO film having a film thickness of 0.5 μm to 1 μm which constitute a pixel electrode is applied to the reflective electrode. A surface of the coating-type ITO film is leveled. A capacitive insulation film is formed on the pixel electrode, and a comb-teeth-shaped common electrode is formed on the capacitive insulation film. When a voltage is applied between the common electrode and the pixel electrode, liquid crystal is controlled by a leaked electric field. Since the common electrode is formed in a planar plane, a thickness of a liquid crystal layer can be made uniform.

摘要： A pixel is formed by sealing an insulating liquid and floating particles in an area defined by a first substrate, a second substrate and partitions. The width of the partition has to be reduced in order to improve the pixel brightness by enlarging a flat electrode. In this case, the height of the partition has to be reduced for retaining the mechanical strength. If the height of the partition is reduced, an area of the partition electrode becomes small, thus failing to retain the memory effect. The planar surface of the partition is then formed into a zigzag shape so as to increase the area of the partition electrode.

摘要翻译： 通过在由第一基板，第二基板和隔板限定的区域中密封绝缘液体和浮动颗粒来形成像素。 必须减小分隔件的宽度，以便通过放大扁平电极来提高像素的亮度。 在这种情况下，为了保持机械强度，必须减小隔板的高度。 如果隔板的高度减小，则分隔电极的面积变小，因此不能保持记忆效果。 然后将隔板的平面形成为锯齿形，以增加分隔电极的面积。
