Abstract:
(EN) Provided is a display device that is capable of preventing detachment of a sealing layer that is for sealing a light-emitting layer and that is interposed between a first partition wall and a second partition wall formed at an end of the sealing layer. An organic EL display device (1) doubly surrounds an end of a sealing layer (30) for sealing a light-emitting element layer (20) by a first bank (34A) and a second bank (35A) that is formed outside the first bank (34A) with a gap therebetween. The outer wall surface (34a) of the first bank (34A) on the second bank (35A) side is formed as a gentle slope which has a slope angle less than that of the inner wall surface (34b) of the first bank (34A) on a side opposed to the second bank (35A) side.
(FR) L'invention concerne un dispositif d'affichage étant capable d'empêcher le détachement d'une couche d'étanchéité qui est destinée à sceller une couche électroluminescente et qui est interposée entre une première paroi de séparation et une seconde paroi de séparation formée au niveau d'une extrémité de la couche d'étanchéité. Un dispositif d'affichage électroluminescent organique (1) entoure doublement une extrémité d'une couche d'étanchéité (30) pour sceller une couche d'élément électroluminescent (20) par une première banque (34A) et une seconde banque (35A) qui est formée à l'extérieur de la première banque (34A) avec un espace entre elles. La surface de paroi externe (34a) de la première banque (34A) sur le côté de la seconde banque (35A) est formée sous la forme d'une pente douce qui a un angle de pente inférieur à celui de la surface de paroi interne (34b) de la première banque (34A) sur un côté opposé au côté de la seconde banque (35A).
(JA) 発光層を封止する封止層の端部に形成された第1隔壁と第2隔壁との間の封止層の剥がれを防止し得る表示装置を提供する。有機EL表示装置(1)は、発光素子層(20)を封止する封止層(30)の端部を第1バンク(34A)と該第1バンク(34A)よりも外側に間隔を有して形成された第2バンク(35A)とによって二重に囲う。第1バンク(34A)における第2バンク(35A)側の外側壁面(34a)が、第1バンク(34A)における第2バンク(35A)側とは反対側の内側壁面(34b)よりも傾斜角度が小さい緩斜面に形成されている。
