Abstract

A light-emitting panel includes a plurality of pixels, a plurality of first regulators, and a plurality of second regulators. The plurality of first regulators extends in a first direction and defines each two of the pixels that are adjacent to each other in a second direction orthogonal to the first direction. The plurality of second regulators extends in the second direction and defines each two of the pixels that are adjacent to each other in the first direction. The plurality of pixels at least includes a first pixel and a second pixel that have different lengths in the first direction from each other and share a light-emitting layer. The first pixel and the second pixel are at least adjacent to each other in the first direction with the second regulator being interposed between the first pixel and the second pixel.

Claims (35)

1. A light-emitting panel comprising:

a display region;

a non-display region provided around the display region;

a plurality of pixels;

a plurality of first regulators, each of which extends in a first direction and defines each two of the pixels that are adjacent to each other in a second direction orthogonal to the first direction; and

a plurality of second regulators, each of which extends in the second direction and defines each two of the pixels that are adjacent to each other in the first direction, wherein

the plurality of pixels at least include a first pixel and a second pixel that have different lengths in the first direction from each other and share a light-emitting layer,

the first pixel and the second pixel are adjacent to each other in the first direction with one of the plurality of second regulators being interposed between the first pixel and the second pixel,

the first pixel and the second pixel are disposed in the display region,

the length of the second pixel is smaller than the length of the first pixel in the first direction,

the second pixel is disposed at a boundary between the display region and the non-display region,

the plurality of second regulators includes a third regulator and a fourth regulator,

the plurality of pixels further includes a third pixel disposed in the non-display region,

the second pixel and the third pixel are adjacent to each other in the first direction with the third regulator being interposed between the second pixel and the third pixel,

a length of the third regulator is larger than a length of the fourth regulator in the first direction,

the plurality of first regulators and the plurality of second regulators extend from a substrate, and

each of the plurality of the second regulators has a height smaller than a height of each of the plurality of first regulators.

2. The light-emitting panel according to claim 1 , wherein

the plurality of pixels is grouped into display pixels each including predetermined number of the pixels,

two of the display pixels that are adjacent to each other in the first direction include a first display pixel and a second display pixel,

the first display pixel includes the first pixel, and

the second display pixel includes the second pixel.

3. The light-emitting panel according to claim 1 , wherein the first pixel and the second pixel are disposed in a gap between two of the first regulators that are adjacent to each other.

4. The light-emitting panel according to claim 3 , wherein the first pixel and the second pixel are disposed along the first regulators.

5. The light-emitting panel according to claim 1 , wherein

the plurality of pixels further include at least a third pixel disposed in the non-display region, and

the third pixel is at least adjacent to the first pixel or the second pixel in the first direction, with another of the plurality of second regulators being interposed between the third pixel and the first pixel or the second pixel.

6. The light-emitting panel according to claim 1 , wherein the light-emitting layer comprises a coating film.

7. The light-emitting panel according to claim 6 , wherein the first pixel and the second pixel share another layer including a coating film, in addition to the light-emitting layer.

8. The light-emitting panel according to claim 5 , wherein the third pixel shares the light-emitting layer with the first pixel or the second pixel.

9. The light-emitting panel according to claim 8 , wherein the third pixel shares, with the first pixel or the second pixel, another layer including a coating film, in addition to the light-emitting layer.

10. The light-emitting panel according to claim 1 , wherein the second regulator has a lyophilic property relatively as compared with the first regulator.

11. An electronic apparatus comprising the light-emitting panel according to claim 1 .

12. The light-emitting panel according to claim 1 , wherein the substrate is provided with a planarization film.

13. The light-emitting panel according to claim 1 , wherein the plurality of first regulators and the plurality of second regulators extend from the substrate except for areas where the plurality of first regulators and the plurality of second regulators cross from a plan view of the light-emitting panel.
