Light-emitting element and illuminating apparatus |
摘要 |
A light-emitting device comprising: an organic electroluminescence element that has a light-emitting surface and emits light from the light-emitting surface; and a structure layer that is provided directly or indirectly on the light-emitting surface of the organic electroluminescence element, wherein the structure layer has a concavo-convex structure on a surface of the structure layer, the surface being opposite to the organic electroluminescence element, the concavo-convex structure including a first streak array extending in a first direction that is parallel to the surface, a second streak array extending in a second direction that is parallel to the surface and intersects the first direction, and a third streak array extending in a third direction that is parallel to the surface and intersects the first direction and the second direction, the concavo-convex structure includes flat surface portions parallel to the light-emitting surface and an inclined surface portion that is inclined with respect to the light-emitting surface, and a projected area formed by projecting the inclined surface portion upon a plane parallel to the flat surface portions in a direction perpendicular to the flat surface portions is 0.1 times or less times a total area of the flat surface portions. |

1. A light-emitting device comprising: an organic electroluminescence element that has a light-emitting surface and emits light from the light-emitting surface; and a structure layer that is provided directly or indirectly on the light-emitting surface of the organic electroluminescence element, wherein
the structure layer has a concavo-convex structure on a surface of the structure layer, the surface of the structure layer being opposite to the organic electroluminescence element, the concavo-convex structure including a first streak array extending in a first direction that is parallel to the surface of the structure layer, a second streak array extending in a second direction that is parallel to the surface of the structure layer and intersects the first direction, and a third streak array extending in a third direction that is parallel to the surface of the structure layer and intersects the first direction and the second direction, the concavo-convex structure includes flat surface portions parallel to the light-emitting surface and an inclined surface portion that is inclined with respect to the light-emitting surface, and a projected area, formed by projecting the inclined surface portion upon a plane parallel to the flat surface portions in a direction perpendicular to the flat surface portions is 0.1 times or less times a total area of the flat surface portions. |
