Abstract:
1. An electrophoretic display device, comprising: a switching element on a substrate including a display area having a pixel region and a non-display area at a periphery of the display area; a passivation layer covering the switching element; a pixel electrode on the passivation layer and connected to the switching element; an electrophoresis film on the pixel electrode and including an ink layer and a base film, wherein the ink layer includes a plurality of charged particles, and the base film is formed of polyethylene terephthalate; a common electrode disposed between the base film and the ink layer for generating an electric field with the pixel electrode to drive the electrophoresis film; and a color filter layer directly on the electrophoresis film, wherein the color filter layer is formed under temperatures of less than 100 degrees of Celsius, wherein the color filter layer includes red, green and blue color filter patterns, and the red, green and blue color filter patterns are formed of color resists including red, green and blue pigments, respectively, wherein each of the color resists includes epoxy of 20 to 40 wt % and acrylic binder of 60 to 80 wt %, and wherein the pixel electrode has a length and a width smaller than the pixel region, each of the red, green and blue color filter patterns has a same length as the pixel region, and each of the red, green and blue color filter patterns has a width equal to or smaller than the pixel electrode, and wherein the red, green and blue color filter patterns are sequentially and alternately arranged along a direction parallel to the width.
