(JA) 発光装置および表示装置
Abstract:
(EN) A blue light emitting layer (13b) in a light emitting device (1), said blue light emitting layer being provided between an anode (16) and a cathode (11), includes blue QD phosphor particles (130b) that emit first blue light (Lb) due to electroluminescence. The light emitting device (1) is also provided with a blue phosphor layer (19b) that emits second blue light (Lb2) by receiving the first blue light (Lb), said second blue light being blue light having a peak wavelength that is longer than that of the first blue light (Lb).
(FR) L'invention concerne une couche électroluminescente bleue (13b) dans un dispositif électroluminescent (1), ladite couche électroluminescente bleue étant disposée entre une anode (16) et une cathode (11), comprenant des particules de luminophore à points quantiques (QD) bleus (130b) qui émettent une première lumière bleue (Lb) par électroluminescence. Le dispositif électroluminescent (1) comprend également une couche de luminophore bleue (19b) qui émet une seconde lumière bleue (Lb2) lors de la réception de la première lumière bleue (Lb), ladite seconde lumière bleue étant une lumière bleue ayant une longueur d'onde de crête qui est supérieure à celle de la première lumière bleue (Lb).
(JA) 発光装置(1)において、陽極(16)と陰極(11)との間に設けられた青色発光層(13b)は、エレクトロルミネッセンスによって第1青色光(Lb)を発する青色QD蛍光体粒子(130b)を含む。発光装置(1)は、第1青色光(Lb)を受けて、当該第1青色光(Lb)よりもピーク波長が長い青色光である第2青色光(Lb2)を発する青色蛍光体層(19b)をさらに備える。
