Abstract

In at least one embodiment of the disclosure, an electrophoreses display device includes a first electrode that is formed in each of a plurality of pixels. A second electrode is formed opposite to the first electrode. An electrophoresis element is sandwiched between the first electrode and the second electrode and has electrophoresis particles that are charged electrically. An adhesive layer is interposed between the electrophoresis element and the first electrode. An insulation layer is formed at a region between each two of the first electrodes that are arrayed adjacent to each other.

Claims (27)

1. An electrophoresis display device having a plurality of pixels that is arrayed in a two-dimensional pattern, the electrophoresis display device comprising:

a first electrode that is formed in each of the pixels;

a second electrode that is formed opposite to the first electrode;

an electrophoresis element provided over the first electrode and sandwiched between the first electrode and the second electrode and having electrophoresis particles that are charged electrically;

an adhesive layer interposed between the electrophoresis element and the first electrode; and

an insulation layer that is formed at a region between each two of the first electrodes that are arrayed adjacent to each other.

2. The electrophoresis display device according to claim 1 , wherein the insulation layer is formed to be in contact with an edge surface of the first electrode.

3. The electrophoresis display device according to claim 1 , wherein the insulation layer is formed not to be in contact with the first electrode.

4. The electrophoresis display device according to claim 1 , wherein the insulation layer protrudes toward the electrophoresis element with respect to the upper surface of the first electrode.

5. The electrophoresis display device according to claim 1 , wherein the insulation layer is formed to extend from the upper surface of one of the above-mentioned two first electrodes that are arrayed adjacent to each other to the upper surface of the other of the above-mentioned two first electrodes that are arrayed adjacent to each other.

6. The electrophoresis display device according to claim 1 , wherein the electrophoresis element is in a capsular form that seals the electrophoresis particles.

7. An electronic apparatus that is provided with the electrophoresis display device according to claim 1 .

8. An electrophoresis display device having a plurality of pixels that is arrayed in a two-dimensional pattern, the electrophoresis display device comprising:

a first electrode that is formed in each of the pixels;

a second electrode that is formed opposite to the first electrode;

an electrophoresis element provided over the first electrode and sandwiched between the first electrode and the second electrode and having electrophoresis particles that are charged electrically;

an adhesive layer interposed between the electrophoresis element and the first electrode; and

an insulation layer that is formed on the first electrode and has an opening over an upper surface of the first electrode.

9. The electrophoresis display device according to claim 8 , wherein the insulation layer is formed to cover a peripheral region of the upper surface of the first electrode.

10. The electrophoresis display device according to claim 8 , wherein the insulation layer protrudes toward the electrophoresis element with respect to the upper surface of the first electrode.

11. The electrophoresis display device according to claim 8 , wherein the electrophoresis element is in a capsular form that seals the electrophoresis particles.

12. An electronic apparatus that is provided with the electrophoresis display device according to claim 8 .

13. An electrophoresis display device having a plurality of pixels that is arrayed in a two-dimensional pattern, the electrophoresis display device comprising:

a first electrode that is formed in each of the pixels;

a second electrode that is formed opposite to the first electrode;

an electrophoresis element that is sandwiched between the first electrode and the second electrode and has electrophoresis particles that are charged electrically; and

an insulation layer that is formed at a region between each two of the first electrodes that are arrayed adjacent to each other, the insulation layer formed so as not to be in contact with the first electrodes.
