Abstract:
(EN) In this display device, a sealing film (23a) that covers an organic EL layer (16) comprises: a first sealing inorganic layer (19) provided so as to cover the organic EL layer (16); a sealing organic layer (20a) provided on the first sealing inorganic layer (19); a second sealing inorganic layer (21a) provided on the sealing organic layer (20a); and a third sealing inorganic layer (22a) provided on the second sealing inorganic layer (21a); a peripheral end surface of the second sealing inorganic layer (21a) conforming to a peripheral end surface of the sealing organic layer (20a). Also, in a frame area (GA), a bank (Ba1) is provided to the lower layer of the sealing organic layer (20a) in a peripheral end part (20aep) of the sealing organic layer (20a) in which routing wirings (W1, W2) extend through and intersect in the frame area (GA).
(FR) Dans le dispositif d'affichage selon la présente invention, un film d'étanchéité (23a) qui recouvre une couche EL organique (16) comprend : une première couche d'étanchéité inorganique (19) disposée de manière à recouvrir la couche EL organique (16) ; une couche d'étanchéité organique (20a) disposée sur la première couche d'étanchéité inorganique (19) ; une deuxième couche d'étanchéité inorganique (21a) disposée sur la couche d'étanchéité organique (20a) ; et une troisième couche d'étanchéité inorganique (22a) disposée sur la deuxième couche d'étanchéité inorganique (21a) ; une surface d'extrémité périphérique de la deuxième couche d'étanchéité inorganique (21a) se conformant à une surface d'extrémité périphérique de la couche d'étanchéité organique (20a). De plus, dans une zone de cadre (GA), un banc (Ba1) est disposé sur la couche inférieure de la couche d'étanchéité organique (20a) dans une partie d'extrémité périphérique (20 aep) de la couche d'étanchéité organique (20a) dans laquelle des câblages de routage (W1. W2) s'étendent à travers la zone de cadre (GA) et se croisent dans cette dernière.
(JA) 有機EL層(16)を覆う封止膜(23a)は、有機EL層(16)を覆うように設けられた第1封止無機層(19)と、第1封止無機層(19)上に設けられた封止有機層(20a)と、封止有機層(20a)上に設けられた第2封止無機層(21a)と、第2封止無機層(21a)上に設けられた第3封止無機層(22a)とを備え、第2封止無機層(21a)の周端面は、封止有機層(20a)の周端面と一致している。また、額縁領域(GA)には、引き回し配線(W1、W2)が当該額縁領域(GA)を延伸し交差する封止有機層(20a)の周端部(20aep)において、バンク(Ba1)が、当該封止有機層(20a)の下層に設けられている。
