Abstract
An electrophoretic display apparatus including a driving array substrate, a color filter layer, and an electrophoretic display film is provided. The driving array substrate has a plurality of display units. The color filter layer is disposed on the driving array substrate. The color filter layer includes a plurality of color filter patterns. Each of the display units corresponds to the color filter patterns of two different colors. The electrophoretic display film is between the driving array substrate and the color filter layer. The electrophoretic display film includes a plurality of display mediums. Each of the display mediums includes an electrophoretic liquid, a plurality of color charged particles, a plurality of black charged particles, and a plurality of white charged particles. A color of the color charged particles is different from colors of the color filter patterns.
