An electrophoretic display apparatus includes a bottom substrate, an electrophoretic layer, a color filter substrate and a spacing layer. The bottom substrate has a drive circuitry layer, and the electrophoretic layer is disposed on the drive circuitry layer of the bottom substrate. The color filter substrate is disposed above the electrophoretic layer, and the spacing layer is disposed between the color filter substrate and the electrophoretic layer. The electrophoretic display apparatus has better display quality.
