Title (EN) DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE
(JA) 表示装置
Abstract:
(EN) A display device comprises a device body that includes: a light-emitting display element comprising a laminate including a plurality of inorganic layers; and a first organic layer (Ha) and a second organic layer (Hb) provided on one surface and the other surface of the light-emitting display element. The lower limit of the film thickness of the first organic layer (Ha) and the second organic layer (Hb) is represented by whichever is greater of −da/0.011+da or db/0.011+da, where da (<0) represents the distance from the neutral plane (N) of the device body to the first-organic-layer (Ha)-side surface of the uppermost inorganic layer (Ia) closest to the first organic layer (Ha) and db (>0) represents the distance from the neutral plane (N) of the device body to the second-organic-layer (Hb)-side surface of the lowermost inorganic layer (Ib) closest to the second organic layer (Hb).
(FR) Un dispositif d'affichage selon l'invention comprend un corps de dispositif qui comprend : un élément d'affichage électroluminescent comprenant un stratifié incluant une pluralité de couches inorganiques ; et une première couche organique (Ha) et une seconde couche organique (Hb) disposées sur une surface et sur l'autre surface de l'élément d'affichage électroluminescent. La limite inférieure de l'épaisseur de film de la première couche organique (Ha) et de la seconde couche organique (Hb) est représentée par la valeur la plus élevée parmi −da/0,011+da et db/0,011+da, où da(<0) représente la distance du plan neutre (N) du corps de dispositif à la surface côté première couche organique (Ha) de la couche inorganique la plus élevée (Ia) la plus proche de la première couche organique (Ha) et db(>0) représente la distance du plan neutre (N) du corps de dispositif à la surface côté seconde couche organique (Hb) de la couche inorganique la plus basse (Ib) la plus proche de la seconde couche organique (Hb).
(JA) 複数の無機層を含む積層体からなる発光表示素子と、発光表示素子の一方及び他方の表面側に設けられた第1有機層(Ha)及び第2有機層(Hb)とを備えた装置本体からなり、装置本体の中立面(N)から第1有機層(Ha)に最も近い無機最上層(Ia)の第1有機層(Ha)側の表面までの距離をd(<0)とし、装置本体の中立面(N)から第2有機層(Hb)に最も近い無機最下層(Ib)の第2有機層(Hb)側の表面までの距離をd(>0)とすると、第1有機層(Ha)及び第2有機層(Hb)の膜厚の下限値は、-d/0.011+dと、d/0.011+dとのうちの大きい方である。
