Abstract
(EN)
In the present invention, an organic layer (120) is located between a first electrode (110) and a second electrode (130) and has a light emitting layer. Spectral distribution of light from the organic layer (120) has a peak (hereinafter referred to as a first peak) located within a range of 540 nm - 570 nm inclusive. The height of the first peak of a first time period in accumulated light emitting time of the light emitting device (10) is lower than the height of the first peak of a second time period, which is longer than the first time period, in accumulated light emitting time of the light emitting device (10).
(FR)
Dans la présente invention, une couche organique (120) est située entre une première électrode (110) et une seconde électrode (130) et a une couche électroluminescente. La distribution spectrale de la lumière provenant de la couche organique (120) a une crête (ci-après désignée par "première crête") située dans une plage de 540 nm à 570 nm inclus. La hauteur de la première crête d'une première période en temps cumulé d'émission de lumière du dispositif électroluminescent (10) est inférieure à la hauteur de la première crête d'une deuxième période, qui est plus longue que la première période, en temps cumulé d'émission de lumière du dispositif électroluminescent (10).
(JA)
有機層(120)は、第1電極(110)と第2電極(130)の間に位置しており、発光層を有している。有機層(120)からの光のスペクトル分布は、540nm以上570nm以下の範囲に位置するピーク(以下、第1ピークと記載)を有している。そして発光装置(10)の累積発光時間が第1時間における第1ピークの高さは、発光装置(10)の累積発光時間が第1時間よりも長い第2時間における第1ピークの高さよりも低い。
