Abstract

A light-emission unit includes a light-emission section, a light extraction surface that extracts light outputted from the light-emission section, and a light-condensing section that is provided on side opposite the light extraction surface, with the light-emission section provided therebetween.

Claims (29)

1. A light-emission unit, comprising:

a light-emission section;

a light extraction surface configured to extract light outputted from the light-emission section; and

a light-condensing section on a side opposite the light extraction surface, wherein

the light-emission section is between the light extraction surface and the light-condensing section,

the light-condensing section comprises at least one projection, and

the projection has a sloped surface or curved surface that faces the light-emission section.

2. The light-emission unit according to claim 1 , wherein the light-condensing section at least at a portion of a periphery of the light-emission section.

3. The light-emission unit according to claim 1 , wherein the light-condensing section includes a plurality of projections concentrically provided around the light-emission section, wherein the plurality of projections include the at least one projection.

4. The light-emission unit according to claim 1 , wherein the light-condensing section includes an antireflection film on a surface of the projection.

5. The light-emission unit according to claim 1 , wherein the light-emission section is placed on a holding section, and the light-condensing section is in the holding section.

6. The light-emission unit according to claim 5 , wherein in the holding section, the light-condensing section is on a surface opposite a surface on which the light-emission section is placed.

7. The light-emission unit according to claim 5 , wherein the holding section includes a sealing resin, and the light-emission section is sealed by the sealing resin.

8. The light-emission unit according to claim 5 , further comprising a plurality of light-emission sections placed in the holding section, and the light-condensing section is provided for each of light-emission elements, wherein the plurality of light-emission sections include the light-emission section.

9. A display, comprising:

a display panel that includes a plurality of light-emission units; and

a drive circuit configured to drive the plurality of light-emission units based on an image signal,

wherein each of the plurality of light-emission units includes:

a light-emission section,

a light extraction surface configured to extract light outputted from the light-emission section, and

a light-condensing section on a side opposite the light extraction surface, wherein

the light-emission section is between the light extraction surface and the light-condensing section,

the light-condensing section comprises at least one projection, and

the projection has a slope surface or curved surface that faces the light-emission section.

10. A light-emission unit, comprising:

a light-emission section;

a light extraction surface configured to extract light outputted from the light-emission section;

a light-condensing section on a side opposite the light extraction surface, wherein the light-emission section is between the light extraction surface and the light-condensing section; and

a reflection member on an outer side of the light-condensing section, wherein the reflection member is opposite the light extraction surface.
