Abstract

A display apparatus includes pixel electrodes disposed on a first base substrate, a second base substrate which faces the first base substrate, color pixels disposed on the second base substrate, the color pixels correspond to the pixel electrodes in a one-to-one correspondence, each color pixel partially covers the corresponding pixel electrode, a common electrode disposed on the second base substrate to cover the pixel electrodes and an electrophoretic layer including a plurality of electrophoretic particles, the electrophoretic layer being interposed between the pixel electrodes and the common electrode.

Claims

1. A display apparatus comprising:

a first base substrate;

a plurality of pixel areas disposed in a matrix on the first base substrate, at least one of the pixel areas including a pixel electrode;

a second base substrate which faces the first base substrate;

a color filter layer disposed on the second base substrate, the color filter layer comprising a plurality of color pixels and having a plurality of holes;

wherein the color pixels correspond to the pixel areas in a one-to-one correspondence and at least one of the holes is disposed between the two adjacent color pixels.

2. The display apparatus as claimed in claim 1, further comprising a black matrix disposed on the second base substrate.

3. The display apparatus as claimed in claim 1, wherein each of the color pixels comprises one of red, green and blue pixels.

4. The display apparatus as claimed in claim 3, wherein the red, green and blue pixels have different area sizes each other.

5. The display apparatus as claimed in claim 4, wherein the green pixel has a smaller area than an area of the red pixel and the blue pixel has a larger area than an area of the red pixel.

6. The display apparatus as claimed in claim 4, wherein the red, green and blue pixels have different widths each other in a cross sectional view.

7. The display apparatus as claimed in claim 3, the red, green and blue pixels have a same thickness.

8. The display apparatus as claimed in claim 1, wherein each of the color pixels is positioned at a central portion of an area of the corresponding pixel area and each of the holes are positioned at an area adjacent to the color pixels.

9. The display apparatus as claimed in claim 1, further comprising a common electrode disposed on the second base substrate to cover the color pixels.
