Title (EN) ORGANIC ELECTROLUMINESCENT ELEMENT
(FR) ÉLÉMENT ÉLECTROLUMINESCENT ORGANIQUE
(JA) 有機電界発光素子
Abstract: front page image
(EN)This organic electroluminescent element is provided with: a transparent electrode that is mainly composed of silver (Ag); a reflective electrode that is formed of a metal; and at least one light emitting layer that is provided between the transparent electrode and the reflective electrode. This organic electroluminescent element is configured such that the difference between the maximum value and the minimum value of element reflectance of light having a wavelength of 450-750 nm is 30% or less.
(FR)Cet élément électroluminescent organique comporte : une électrode transparente qui est principalement composée d'argent (Ag) ; une électrode réfléchissante qui est formée en un métal; et au moins une couche électroluminescente qui est disposée entre l'électrode transparente et l'électrode réfléchissante. Cet élément électroluminescent organique est configuré de telle sorte que la différence entre la valeur maximale et la valeur minimale de facteur de réflexion élémentaire de lumière ayant une longueur d'onde de 450 à 750 nm est de 30 % ou moins.
(JA) 銀(Ag)を主成分とする透明電極と、金属からなる反射電極と、透明電極と反射電極との間に設けられた少なくとも1層以上の発光層とを備え、波長450nm~750nmの光における素子反射率の最大値と最小値との差が30%以内である有機電界発光素子を構成する。
