Definitions
- the present invention relates to an organic EL display device and a method for manufacturing the organic EL display device.
- FIG. 7 is an enlarged cross-sectional view of a modified example near the bank of the display panel shown in FIG.
- the light absorption layer 108 is a single layer body, whereas in the present modification, the light absorption layer 108 is a stacked body including a plurality of layers.
- the light absorption layer 108 includes a first light absorption layer 108a, a second light absorption layer 108b, and a third light absorption layer 108c in this order from the side where the bank 112 is disposed.
- absorption portions 109a, 109b, and 109c are formed in portions overlapping the bank 112 in plan view, respectively.
- the absorption portion 109 is selectively formed at a location where the light emission is strong.
- the absorbing portion 109 is formed so as to cover at least the central portion 112 b of the bank 112, and is not formed on the end portion (slope) 112 a of the bank 112. This form is preferable, for example, in that the difficulty of forming the absorbing portion 109 is low.
- FIG. 8C shows that the absorbing portion 109 is low.

Abstract
L'invention concerne un dispositif d'affichage électroluminescent organique dans lequel les défauts dus à un courant de fuite sont réduits. Ce dispositif d'affichage électroluminescent organique comprend : un substrat ; une pluralité de pixels positionnés sur le substrat ; une électrode inférieure disposée pour chaque pixel de la pluralité de pixels ; un banc agencé entre des électrodes inférieures adjacentes et définissant la pluralité de pixels ; une couche de matériau organique disposée sur le dessus de l'électrode inférieure et du banc ; une électrode supérieure disposée sur la couche de matériau organique ; et une couche d'absorption de lumière disposée sur l'électrode supérieure. Une section d'absorption qui absorbe la lumière émise par la couche de matériau organique est formée dans une partie de la couche d'absorption de lumière qui, dans une vue en plan, chevauche le banc.
