Abstract
There is provided a display device including a light-emitting element body part, a low refractive index layer part which is provided over a light output surface of the light-emitting element body part and has a first refractive index, and a packaging member which is provided to seal the light-emitting element body part and the low refractive index layer part inside the packaging member, has a planar light output surface, and has a second refractive index which is greater than the first refractive index.
Claims18
1:
- A display device comprising:
- a light-emitting element provided on a substrate;
- a layer including a first refractive index, the layer is provided over the light-emitting element;
- a resin member provided over the light-emitting element and the layer;
- and
- a first light-shielding layer provided over the resin member,
- wherein the resin member has a planar light output surface and has a second refractive index which is greater than the first refractive index, and
- wherein the first light-shielding layer has a first opening and the first opening faces the light-emitting element.
5 more elements
2:
- The display device according to claim 1, further comprising a screen provided over the resin member.
3:
- The display device according to claim 2, wherein the first light-shielding layer is provided on the screen.
4:
