Abstract: This organic electroluminescent element includes: a substrate having light transmissivity; and an organic light emitting body including a first electrode, an organic light emitting layer, and a second electrode. The organic electroluminescent element includes a resin part which includes a first resin layer and a second resin layer between the substrate and the organic light emitting body. The resin part includes an uneven interface between the first resin layer and the second resin layer. The uneven interface includes a first uneven structure and a second uneven structure, and protrusions and recesses of the second uneven structure are smaller than protrusions and recesses of the first uneven structure. The second uneven structure has a random arrangement of the protrusions and recesses thereof.

Abstract: A light-emitting device includes: a light-emitting layer; a first layer located on a light-emitting side of the light-emitting layer; and a second layer located on a light-emitting side of the first layer, and in contact with the first layer. A concavo-convex structure composed of a plurality of convex portions having two or more steps is formed at a boundary between the first layer and the second layer, a refractive index of the first layer is higher than a refractive index of the second layer, and a concavo-convex pattern of the concavo-convex structure is a pattern formed by a space-filling curve or a fractal tiling pattern.

Abstract: An organic electroluminescent element includes at least one light emitting layer, a high refractive index layer (first layer), and a low refractive index layer (second layer). An uneven structure including a plurality of protrusions each having two or more steps is provided at an interface between the high refractive index layer and the low refractive index layer. The organic electroluminescent element includes a protective layer. The protective layer is a layer disposed between the second layer (low refractive index layer) and a light-exiting surface of the organic electroluminescent element or is the second layer (low refractive index layer). Relationships expressed as n0

Abstract: An illumination device is provided that provides a uniform luminance of a light emitting surface and is less likely to cause a fringe pattern. The illumination device includes a mounting substrate on which multiple LEDs are mounted, a planar light guide plate that receives and guides at least a part of emission light emitted from the multiple LEDs, and multiple optical structures that are provided at intervals on one surface of the light guide plate and that change a traveling direction of light. The multiple optical structures include a first arrangement section that is provided on the LED side, a second arrangement section that is provided on a side away from the LEDs, and a third arrangement section that is provided between the first arrangement section and the second arrangement section.
