See full text

A solid-state light-emitting element includes a structure body having a property of transmitting visible light and an uneven structure on each of the top side and the bottom side thereof; a high refractive index material layer provided on one surface of the structure body; and a light-emitting body with a refractive index of greater than or equal to 1.6 provided over the high refractive index material layer. One surface of the high refractive index material layer is flatter than the other surface thereof which is in contact with the structure body. The refractive index of the high refractive index material layer is greater than or equal to 1.6. The refractive index of the structure body is greater than 1.0 and less than that of the high refractive index material layer.
