Document Type and Number:
WIPO Patent Application WO/2017/037987
Kind Code:
A1
Abstract:
This light-emitting device (1, 2) comprises: a light-emitting layer (111); a first layer (121, 221) disposed on the light exit side of the light-emitting layer (111); and a second layer (122, 222) disposed on the light exit side of the first layer (121, 221) and adjacent to the first layer (121, 221). A raised and recessed structure comprising a plurality of raised portions (120a, 220a), each having two or more steps, is formed at the boundary between the first layer (121, 221) and the second layer (122, 222). The refractive index of the first layer (121, 221) is greater than the refractive index of the second layer (122, 222). The raising and recessing pattern of the raised and recessed structure is a pattern formed by a space filling curve or a fractal tiling pattern.
