Abstract

A display device includes a substrate having a plurality of transmissive regions aligned in a first direction and a second direction, a plurality of first wiring lines on the substrate extending in the first direction, a plurality of second wiring lines on the substrate extending in the second direction, and a plurality of light emitting sections disposed on the substrate. Each of the transmissive regions is surrounded by the first and second wiring lines. The light emitting sections include a first light emitting section and a second light emitting section. At least part of the first light emitting section is located in a region that is adjacent to the transmissive regions and overlap one of the first wiring lines. At least part of the second light emitting section is located in a region that is adjacent to the transmissive regions and overlap one of the second wiring lines.

Claims (23)

1. A display device comprising:

a substrate having a plurality of transmissive regions aligned in a first direction and a second direction that intersects the first direction;

a plurality of first wiring lines disposed on the substrate and running in the first direction;

a plurality of second wiring lines disposed on the substrate and running in the second direction; and

a plurality of light emitting sections disposed on the substrate,

wherein each of the transmissive regions is surrounded by the first wiring lines and the second wiring lines,

each of the light emitting sections is located at a center of four of the transmissive regions adjacent to each other in the first and second directions and continuously has a first portion running through spaces between two pairs of the transmissive regions adjacent to each other in the first direction and a second portion running through spaces between two pairs of the transmissive regions adjacent to each other in the second direction.

2. The display device according to claim 1 , wherein each of the light emitting sections further has a third portion, and

the third portion runs from the first portion toward both sides in the first direction, runs from the second portion toward both sides in the second direction, and connects the first portion with the second portion.

3. The display device according to claim 1 , further comprising:

an interlayer film provided between the plurality of light emitting sections and the substrate; and

a plurality of light-transmissive planarizing films provided in the plurality of transmissive regions,

wherein the interlayer film does not overlap the plurality of transmissive regions in plan view.

4. The display device according to claim 3 , wherein the interlayer film has a side surface facing the planarizing film, and

each of the light emitting sections is provided so as to reach the side surface.

5. The display device according to claim 3 , wherein the plurality of light emitting sections include at least a blue light emitting section that emits blue light,

each of the transmissive regions is adjacent to a first wiring line group including some of the first wiring lines and a second wiring line group including some of the second wiring lines,

one of the first wiring line group and the second wiring line group is wider than an other of the first wiring line group and the second wiring line group, and

the blue light emitting section overlaps the one of the first wiring line group and the second wiring line group in plan view.

6. The display device according to claim 3 , wherein the plurality of light emitting sections include at least a blue light emitting section that emits blue light,

each of the transmissive regions is adjacent to a first wiring line group including some of the first wiring lines and a second wiring line group including some of the second wiring lines,

one of the first wiring line group and the second wiring line group is narrower than an other of the first wiring line group and the second wiring line group, and

the blue light emitting section overlaps the one of the first wiring line group and the second wiring line group in plan view.
