Abstract

There is provided a display device including a plurality of light-emitting elements that are disposed on a first substrate, and a guide member that is disposed in a boundary between pixel regions corresponding to the light-emitting elements and guides light emitted from each of the light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the light-emitting elements.

First claim

The invention claimed is:

1. A display device comprising:
a plurality of light-emitting elements that are disposed on a first substrate;
a guide member that is disposed in a boundary between pixel regions corresponding to the plurality of light-emitting elements and is configured to guide light emitted from each of the plurality of light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the plurality of light-emitting elements; and
a color filter that is disposed in one of the pixel regions on the second substrate and surrounded by the guide member,
wherein the guide member is configured to guide the light that is emitted at least between the color filter and the first substrate, and
wherein the guide member penetrates the color filter and the second substrate.

2. A display device comprising:
a plurality of light-emitting elements that are disposed on a first substrate;
a guide member that is disposed in a boundary between pixel regions corresponding to the plurality of light-emitting elements and is configured to guide light emitted from each of the plurality of light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the plurality of light-emitting elements;
a color filter that is disposed in one of the pixel regions on the second substrate and surrounded by the guide member; and
a protective layer of the plurality of light-emitting elements that is formed on the first substrate,
wherein the guide member comes into contact with the protective layer,
wherein the guide member is configured to guide the light that is emitted at least between the color filter and the first substrate, and
wherein the guide member contacts a surface of the color filter that is facing the first substrate.

3. The display device according to claim 2 , wherein the guide member penetrates the color filter and contacts a surface of the second substrate.

4. The display device according to claim 2 , further comprising:
an adhesive layer that is interposed between the protective layer and the second substrate,

wherein the guide member penetrates the adhesive layer.

5. A display device comprising:
a plurality of light-emitting elements that are disposed on a first substrate;
a guide member that is disposed in a boundary between pixel regions corresponding to the plurality of light-emitting elements and is configured to guide light emitted from each of the plurality of light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the plurality of light-emitting elements;
a color filter that is disposed in one of the pixel regions on the second substrate and surrounded by the guide member;
a protective layer of the plurality of light-emitting elements that is formed on the first substrate; and
an adhesive layer that is interposed between the protective layer and the second substrate,
wherein the guide member penetrates into the adhesive layer,
wherein the guide member is configured to guide the light that is emitted at least between the color filter and the first substrate, and
wherein the guide member contacts a surface of the color filter that is facing the first substrate.

6. The display device according to claim 5 , wherein the guide member penetrates the color filter and contacts a surface of the second substrate.

7. A display device comprising:
a plurality of light-emitting elements that are disposed on a first substrate;
a guide member that is disposed in a boundary between pixel regions corresponding to the plurality of light-emitting elements and is configured to guide light emitted from each of the plurality of light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the plurality of light-emitting elements; and
a color filter that is disposed in one of the pixel regions on the second substrate and surrounded by the guide member,
wherein the guide member is configured to guide the light that is emitted at least between the color filter and the first substrate,
wherein a full cross-section of the guide member has a tapered shape opened toward a side of the first substrate.

8. The display device according to claim 7 , wherein the guide member penetrates the color filter and contacts a surface of the second substrate.

9. The display device according to claim 7 , wherein the guide member contacts a surface of the color filter on a side of the first substrate.

10. A display device comprising:
a plurality of light-emitting elements that are disposed on a first substrate;
a guide member that is disposed in a boundary between pixel regions corresponding to the plurality of light-emitting elements and is configured to guide light emitted from each of the plurality of light-emitting elements between the first substrate and a second substrate facing the first substrate in a main light emission direction of each of the plurality of light-emitting elements; and
a color filter that is disposed in one of the pixel regions on the second substrate and surrounded by the guide member,
wherein the guide member is configured to guide the light that is emitted at least between the color filter and the first substrate,
wherein a cross-section of the guide member has a tapered shape opened toward a side of the second substrate, and
wherein the guide member contacts a surface of the color filter that is facing the first substrate.

11. The display device according to claim 10 , wherein the guide member penetrates the color filter and contacts a surface of the second substrate.
