Light-enhancing structure for electrophoretic display

1. A display device comprising:

(a) a display fluid layer comprising micro-containers filled with a display fluid, said display fluid layer is sandwiched between a first substrate layer and a second substrate layer, wherein the first substrate layer is on the viewing side and the second substrate layer comprises electrodes which drive the display fluid laterally; and

(b) a light-enhancing layer between the display fluid layer and the second substrate layer,

wherein:

the display fluid is an electrophoretic fluid comprising charged pigment particles dispersed in a solvent or solvent mixture and the display device is capable of showing a color by laterally switching the charged pigment particles, and

the light-enhancing layer is an array of microlens.

2. The display device of claim 1 , wherein the electrodes are in-plane electrodes.

3. The display device of claim 2 , wherein the first substrate layer comprises a common electrode.

4. The display device of claim 1 , wherein the first substrate layer comprises a common electrode and the second substrate layer comprises a plurality of bottom electrodes and in-plane electrodes.

5. The display device of claim 1 , wherein the electrodes are of different sizes.

6. The display device of claim 1 , wherein the charged pigment particles are of one color and carrying the same charge polarity.

7. The display device of claim 1 , wherein the charged pigment particles are of two colors and carrying opposite charge polarities.

8. The display device of claim 1 , further comprising a color layer.
