Abstract
(EN) A display device is provided. A display device includes: a first dam member, a first support member, a second dam member, and a second support member which are positioned in a non-display area on a base part; a light-emitting element disposed in a display area of the base part; a first encapsulation layer positioned on the light-emitting element; a wavelength conversion pattern disposed on the first encapsulation layer to overlap the light-emitting element; a color filter which is disposed on the wavelength conversion pattern and overlaps the wavelength conversion pattern; and a second encapsulation layer positioned on the color filter; wherein: the first dam member is positioned between the first support member and the display area; the first support member is positioned between the second dam member and the first dam member; the second dam member is positioned between the second support member and the first support member; the end of an inorganic layer included in the first encapsulation layer is positioned between the first support member and the first dam member; and the end of an inorganic layer included in the second encapsulation layer is positioned between the second support member and the second dam member.
(FR) L'invention concerne un dispositif d'affichage. Un dispositif d'affichage comprend : un premier élément de barrage, un premier élément de support, un second élément de barrage et un second élément de support qui sont positionnés dans une zone de non-affichage sur une partie de base ; un élément électroluminescent disposé dans une zone d'affichage de la partie de base ; une première couche d'encapsulation positionnée sur l'élément électroluminescent ; un motif de conversion de longueur d'onde disposé sur la première couche d'encapsulation pour chevaucher l'élément électroluminescent ; un filtre de couleur qui est disposé sur le motif de conversion de longueur d'onde et chevauche le motif de conversion de longueur d'onde ; et une seconde couche d'encapsulation positionnée sur le filtre de couleur ; le premier élément de barrage étant positionné entre le premier élément de support et la zone d'affichage ; le premier élément de support est positionné entre le second élément de barrage et le premier élément de barrage ; le second élément de barrage est positionné entre le second élément de support et le premier élément de support ; l'extrémité d'une couche inorganique incluse dans la première couche d'encapsulation est positionnée entre le premier élément de support et le premier élément de barrage ; et l'extrémité d'une couche inorganique incluse dans la seconde couche d'encapsulation est positionnée entre le second élément de support et le second élément de barrage.
