Abstract

An electrophoretic display device includes: an electrophoretic layer which is sandwiched between a first substrate and a second substrate, wherein a disposition area of the electrophoretic layer is constituted by a display area and a sacrifice display area which is provided to surround the display area, and at the second substrate, a printed area which is set outside the display area in a plan view and overlaps an outer peripheral portion of the sacrifice display area is provided.

Claims (12)

1. An electrophoretic display device comprising:

an electrophoretic layer which is sandwiched between a first substrate and a second substrate,

wherein a disposition area of the electrophoretic layer is constituted by a display area and a sacrifice display area which is provided to surround the display area, and

at the second substrate, a printed area which is set outside the display area in a plan view and overlaps an outer peripheral portion of the sacrifice display area is provided,

wherein in a case where position misalignment of the central portion of the printed area and the central portions of the display area and the sacrifice display area has occurred, the pixel structure of each of the display area and the sacrifice display area is driven so as to make a portion of the display area function as the sacrifice display area and make a portion of the sacrifice display area function as the display area.

2. The electrophoretic display device according to claim 1 , wherein the printed area is provided at the face side of the second substrate, which faces the first substrate.

3. An electronic apparatus provided with the electrophoretic display device according to claim 2 .

4. The electrophoretic display device according to claim 1 , wherein the printed area is printed with ink containing electrophoretic particles of the electrophoretic layer.

5. An electronic apparatus provided with the electrophoretic display device according to claim 4 .

6. The electrophoretic display device according to claim 1 , wherein the display area has a pixel structure in which a plurality of electrodes is regularly disposed, and the sacrifice display area has the same pixel structure as that of the display area.

7. An electronic apparatus provided with the electrophoretic display device according to claim 6 .

8. An electronic apparatus provided with the electrophoretic display device according to claim 1 .
