Light emitting device and display device

A display device comprising:

• a display panel driven on the basis of an image signal;
• and
• a light emitting device for emitting light which illuminates the display panel,
• wherein the light emitting device has a substrate and has, on the surface opposite to the display panel of the substrate, a first electrode, a light-emitting layer, and a second electrode in order from the substrate side,
• the substrate has a first three-dimensional structure including a plurality of projections in nano order on the surface of the first electrode side, and
• at least the first electrode out of the first electrode, the light-emitting layer, and the second electrode has a second three-dimensional structure modeled on the projections in the first three-dimensional structure on the surface on the side opposite to the substrate.

A display device comprising:

• a display panel driven on the basis of an image signal;
• and
• a light emitting device for emitting light which illuminates the display panel,
• wherein the light emitting device has a substrate and has, on the surface on the side of the display panel of the substrate, a first electrode, a light-emitting layer, a second electrode, and a barrier layer in order from the substrate side,
• the substrate has a first three-dimensional structure including a plurality of projections in nano order on the surface of the first electrode side, and
• the first electrode, the light-emitting layer, the second electrode, and the barrier layer have a second three-dimensional structure modeled on the projections in the first three-dimensional structure on the surface on the side opposite to the substrate.
