Title (EN) LIGHT-EMITTING DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT
(JA) 発光装置
Abstract:
(EN) 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.
(FR) Ce dispositif électroluminescent (1, 2) comprend : une couche électroluminescente (111) ; une première couche (121, 221) disposée du côté sortie de lumière de la couche électroluminescente (111) ; et une seconde couche (122, 222) disposée du côté sortie de lumière de la première couche (121, 221) et adjacente à la première couche (121, 221). Une structure en relief et en creux comprenant une pluralité de parties en relief (120a, 220a), ayant chacune deux ou plusieurs étages, est formée au niveau de la limite entre la première couche (121, 221) et de la seconde couche (122, 222). L'indice de réfraction de la première couche (121, 221) est supérieur à l'indice de réfraction de la seconde couche (122, 222). Le motif en relief et en creux de la structure en relief et en creux est un motif constitué d'une courbe de remplissage d'espace ou un motif de mosaïque fractale.
(JA) 発光装置(1、2)は、発光層(111)と、発光層(111)の光出射側に配置される第1の層(121、221)と、第1の層(121、221)の光出射側に配置され、且つ、第1の層(121、221)に接して配置される第2の層(122、222)とを備え、第1の層(121、221)と第2の層(122、222)との境界には、2段以上の段差を有する複数の凸部(120a、220a)からなる凹凸構造が形成されており、第1の層(121、221)の屈折率は、第2の層(122、222)の屈折率よりも大きく、凹凸構造の凹凸パターンは、空間充填曲線によって形成されたパターン又はフラクタルタイリングパターンである。
