Electrophoretic display device

1. An electrophoretic display device comprising:

a substrate including a plurality of pixels;

a first pixel electrodes on the substrate;

a second pixel electrodes to be slit on each first electrode; and

an electrophoretic film disposed on the second pixel electrodes,

wherein the pixel is included of a red sub-pixel, a green sub-pixel and a blue sub-pixel,

wherein the second pixel electrodes on the red, green and blue sub-pixels are different from each other in width.

2. The electrophoretic display device of claim 1 , wherein the slit width of the second pixel electrode for the green sub-pixel is wider than that for the blue sub-pixel and is narrower than that for the red sub-pixel.

3. The electrophoretic display device of claim 1 , further comprising:

first transistors including drain electrodes connected to each first pixel electrode; and

second transistors including drains electrodes connected to each second pixel electrode.

4. The electrophoretic display device of claim 1 , wherein each of the second pixel electrodes receives one of positive and negative polarity voltages having a fixed pulse width.

5. The electrophoretic display device of claim 1 , wherein each of the first pixel electrodes receives a signal including a pulse-width-modulated positive polarity voltage, a negative polarity voltage, and a reference voltage.

6. The electrophoretic display device of claim 1 , further comprising an insulation film, on the electrophoretic film, including a common electrode disposed thereon.

7. The electrophoretic display device of claim 6 , further comprising a light correction film on the insulation film changing a light path to enlarge a viewing angle.

8. The electrophoretic display device of claim 7 , wherein the light correction film includes an embossed pattern on its surface.
