摘要:
An electrophoretic display includes a lower substrate, an upper substrate, a color display layer on the lower substrate, a pixel electrode on the lower substrate, and a common electrode on the lower substrate or the upper substrate. The common electrode does not overlap the pixel electrode, and an electrophoretic active layer having a dispersion medium and electrophoretic particles is arranged between the lower substrate and the upper substrate. The electrophoretic active layer is a single-polarity electrophoretic particle system, and grayscales are generated depending on the number of electrophoretic particles arranged in a portion of the electrophoretic active layer corresponding to the pixel electrode. The position of the electrophoretic particles is controlled by the magnitude of the electric field applied between the pixel electrode and the common electrode.
