Abstract
(EN) The display device comprises: a plurality of light emission layers, each of which can emit light in a reference direction perpendicular to a light emission surface; and a shielding part that can shield a portion of the light traveling from the light emission surface in a direction inclined in relation to the reference direction, the plurality of light emission layers each including a first light emission layer that can emit light having a first peak wavelength, and a second light emission layer that can emit light having a second peak wavelength that is longer than the first peak wavelength, the first light emission layer having a greater proportion than the second light emission layer of the portion of the light that can be shielded by the shielding part in relation to the light traveling in at least one specified direction among the inclined directions.
(FR) La présente invention concerne un dispositif d'affichage qui comprend : une pluralité de couches d'émission de lumière, chacune d'elles pouvant émettre de la lumière dans une direction de référence perpendiculaire à une surface d'émission de lumière ; et une partie de blindage qui peut bloquer une partie de la lumière se déplaçant à partir de la surface d'émission de lumière dans une direction inclinée par rapport à la direction de référence, la pluralité de couches d'émission de lumière comprenant chacune une première couche d'émission de lumière qui peut émettre de la lumière ayant une première longueur d'onde de pic, et une seconde couche d'émission de lumière qui peut émettre de la lumière ayant une seconde longueur d'onde de pic qui est plus longue que la première longueur d'onde de pic, la première couche d'émission de lumière ayant une proportion plus grande que celle qu'a la seconde couche d'émission de lumière de la partie de la lumière qui peut être bloquée par la partie de blindage par rapport à la lumière se déplaçant dans au moins une direction spécifiée parmi les directions inclinées.
(JA) 表示装置は、それぞれが発光面に垂直な基準方向に光を発することができる複数の発光層と、前記発光面から前記基準方向に対して傾斜した方向に進む光のうちの一部の光を遮ることができる遮光部と、を備え、前記複数の発光層は、第1ピーク波長を有する光を発することができる第1発光層と、前記第1ピーク波長よりも長い第2ピーク波長を有する光を発することができる第2発光層と、を含み、前記第1発光層は、前記第2発光層に比較して、前記傾斜した方向のうちの少なくとも1つの特定方向に進む光に対する前記遮光部に遮光され得る前記一部の光の割合が大きい。
