Abstract

There is provided a display device including: a pixel region that includes a plurality of pixels arranged in a matrix; and a peripheral region outside of the pixel region. The pixel region includes first liquid-repellent parts in inter-column regions between the plurality of pixels. The peripheral region includes second liquid-repellent parts that are continuous with the first liquid-repellent parts.

Claims (38)

1. A display device, comprising:

a pixel region that includes a plurality of pixels arranged in a matrix; and

a peripheral region outside of the pixel region,

wherein the pixel region includes first liquid-repellent parts in inter-column regions between the plurality of pixels, and

the peripheral region includes second liquid-repellent parts that are continuous with the first liquid-repellent parts.

2. The display device according to claim 1 ,

wherein the first liquid-repellent parts and the second liquid-repellent parts form a closed frame shape that surrounds one or more columns of the plurality of pixels.

3. The display device according to claim 1 ,

wherein the pixel region includes first lyophilic parts in inter-row regions and the inter-column regions between the plurality of pixels, the first lyophilic parts being surrounded by the first liquid-repellent parts, and

the peripheral region includes second lyophilic parts that are surrounded by the second liquid-repellent parts and are continuous with the first lyophilic parts.

4. The display device according to claim 3 ,

wherein the second lyophilic parts include a recess, and the recess includes a bottom surface whose level is lower than a level of an upper surface of the first lyophilic parts.

5. The display device according to claim 3 ,

wherein the second lyophilic parts include a widened section in which an interval between the second liquid-repellent parts is larger than an interval between the first liquid-repellent parts.

6. The display device according to claim 5 ,

wherein, in the widened section, the interval between the second liquid-repellent parts is gradually increased as goes far from the first liquid-repellent parts in a longitudinal direction of the first liquid-repellent parts.

7. The display device according to claim 5 ,

wherein the plurality of pixels include a first-color pixel column and a second-color pixel column, and

the widened section inside the first liquid-repellent parts and the second liquid-repellent parts that surround the first-color pixel column is located along a same side of the pixel region as the widened section inside the first liquid-repellent parts and the second liquid-repellent parts that surround the second-color pixel column.

8. The display device according to claim 5 ,

wherein the plurality of pixels include a first-color pixel column and a second-color pixel column,

the widened section inside the first liquid-repellent parts and the second liquid-repellent parts that surround the first-color pixel column is located along one of two opposite sides of the pixel region, and

the widened section inside the first liquid-repellent parts and the second liquid-repellent parts that surround the second-color pixel column is located along another of the two opposite sides of the pixel region.

9. The display device according to claim 1 ,

wherein the peripheral region includes third liquid-repellent parts outside of pixel columns located at both ends in a row direction of the plurality of pixels.

10. The display device according to claim 9 ,

wherein the peripheral region includes a trench that surrounds the second liquid-repellent parts and the third liquid-repellent parts.

11. The display device according to claim 10 ,

wherein the peripheral region includes a sealing section, and

the trench is provided in a region between the sealing section and the pixel region.

12. The display device according to claim 1 , wherein the peripheral region includes a bead formation region provided on at least one of an upper side of the pixel region and a lower side of the pixel region, the bead formation region extending in a longitudinal direction of a row of the pixels.

13. The display device according to claim 12 , wherein the bead formation region includes second lyophilic parts that are surrounded by the second liquid-repellent parts.

14. The display device according to claim 12 , further comprising a bead of ink formed on and extending from first lyophilic parts of the pixel region to the second lyophilic parts of the peripheral region, the first lyophilic parts provided in inter-row regions and inter-column regions between the plurality of pixels.

15. An electronic apparatus provided with a display device, the display device comprising:

a pixel region that includes a plurality of pixels arranged in a matrix; and

a peripheral region outside of the pixel region,

wherein the pixel region includes first liquid-repellent parts in inter-column regions between the plurality of pixels, and

the peripheral region includes second liquid-repellent parts that are continuous with the first liquid-repellent parts.
