ABSTRACT:
A color filter substrate includes a base substrate, a color filter layer and an electrophoretic layer. A partition wall section is formed on a first surface of the base substrate. The partition wall section divides the base substrate into a transparent area and a light-blocking area to define a pixel space in the transparent area. The color filter layer is formed in the transparent area. The electrophoretic layer is formed in the pixel space. The electrophoretic layer includes a capsule with a plurality of electrophoretic particles. Therefore, the partition wall section thereby forms the pixel space corresponding to a pixel part, and an electrophoretic layer is infiltrated into the pixel space, so that reflecting ratio and color reproducibility may be enhanced.
