Abstract: front page image
(EN)Provided is an organic LED element wherein an extraction efficiency is improved up to 80% of emission light at maximum. The organic LED element is provided with a light transmitting substrate. The light transmitting substrate is provided with a light transmitting glass substrate; a scattering layer composed of a base material, which is formed on the glass substrate and has a first refractive index to at least one wavelength of transmitting light, and a glass, which is scattered in the base material and has a plurality of scattering materials having a second refractive index different from that of the base material; and a light transmitting electrode, which is formed on the scattering layer and has a third refractive index higher than the first refractive index. Distribution of the scattering materials in the scattering layer is reduced toward a light transmitting electrode.
(FR)L'invention concerne un élément de DEL organique dans lequel un rendement d'extraction est amélioré jusqu'à 80 % de lumière d'émission au maximum. L'élément de DEL organique comporte un substrat transmettant la lumière, le substrat transmettant la lumière étant pourvu d'un substrat en verre transmettant la lumière ; une couche de diffusion composée d'un matériau de base, qui est formée sur le substrat en verre et a un premier indice de réfraction à au moins une longueur d'onde de lumière d'émission, et d'un verre, qui est diffusé dans le matériau de base et a une pluralité de matériaux de diffusion ayant un second indice de réfraction différent de celui du matériau de base ; et une électrode transmettant la lumière, qui est formée sur la couche de diffusion et a un troisième indice de réfraction supérieur au premier indice de réfraction. La distribution des matériaux de diffusion dans la couche de diffusion est réduite en direction d'une électrode transmettant la lumière.
(JA) 本発明は、取り出し効率を最大で発光光の80%まで向上した有機LED素子を提供することを企図し、透光性のガラス基板と、前記ガラス基板上に形成され、透過する光の少なくとも1波長に対して第1の屈折率を有するベース材と、前記ベース材中に分散された、前記ベース材と異なる第2の屈折率を有する複数の散乱物質とを具備したガラスからなる散乱層と、前記散乱層上に形成され、前記第1の屈折率より高い第3の屈折率を有する透光性電極とを具備し、前記散乱層内における前記散乱物質の分布は前記透光性電極に向かって小さくなっている透光性基板を提供する。
