Title
(EN) COLOR CONVERSION SUBSTRATE AND ORGANIC EL DISPLAY USING SAME
(FR) SUBSTRAT DE CONVERSION DE COULEUR ET AFFICHEUR EL ORGANIQUE L'UTILISANT

Abstract
(EN)
Disclosed is a color conversion substrate for an organic EL display panel characterized in that the refractive index of the bank that surrounds a color conversion layer is substantially lower than that of the color conversion layer in a CCM-type, full-color organic EL display. By making the refractive indices of the multiplicity of banks formed at the interfaces between the different color filter layers lower than the refractive index of the color conversion layer, it is possible to improve the light output efficiency compared with a conventional CCM-type, full-color organic EL light-emitting display panel without adding a manufacturing process.
(FR)
L'invention concerne un substrat de conversion de couleur pour un panneau d'affichage EL organique caractérisé en ce que l'indice de réfraction du banc qui entoure une couche de conversion de couleur est sensiblement inférieur à celui de la couche de conversion de couleur dans un afficheur EL organique pleine couleur de type CCM. En rendant les indices de réfraction de la multiplicité de bancs formés au niveau des interfaces entre les différentes couches de filtre de couleur inférieurs à l'indice de réfraction de la couche de conversion de couleur, il est possible d'améliorer le rendement de sortie de lumière par rapport à un panneau d'affichage électroluminescent EL organique pleine couleur de type CCM classique sans ajouter de procédé de fabrication.
(JA)
 CCM方式フルカラー有機ELディスプレイにおいて、色変換層を囲むバンクの屈折率が色変換層より十分低いことを特徴とする有機ELディスプレイパネル用色変換基板を提供する。異種のカラーフィルタ層の境界の上に形成された複数のバンクの屈折率を色変換層の屈折率より低くすることにより、製造プロセスを追加することなく、従来のCCM方式フルカラー有機EL発光ディスプレイパネルに比べ、光取り出し効率を向上することができる。
