Abstract
(EN)
A display panel, a mask plate, and a display device. The device comprises: a substrate, a first flexible layer, a first inorganic layer and a second inorganic layer sequentially stacked from bottom to top, wherein a crack-blocking structure is provided on the first flexible layer, and comprises a cutting portion and inwardly recessed portions on both sides of the cutting portion; the first inorganic layer and the second inorganic layer are cut off at the opening of the inwardly recessed portion; and when the cutting portion cuts a display panel, the inwardly recessed portion is used to prevent cracks in the first inorganic layer and the second inorganic layer from extending to both sides of the crack blocking structure.
(FR)
L'invention concerne un panneau d'affichage, une plaque de masque et un dispositif d'affichage. Le dispositif comprend : un substrat, une première couche flexible, une première couche inorganique et une seconde couche inorganique empilées séquentiellement de bas en haut, une structure de blocage de fissure étant disposée sur la première couche flexible, et comprenant une partie de découpe et des parties évidées vers l'intérieur sur les deux côtés de la partie de découpe ; la première couche inorganique et la seconde couche inorganique sont découpées au niveau de l'ouverture de la partie évidée vers l'intérieur ; et lorsque la partie de découpe découpe un panneau d'affichage, la partie évidée vers l'intérieur est utilisée pour empêcher des fissures dans la première couche inorganique et la seconde couche inorganique de s'étendre vers les deux côtés de la structure de blocage de fissure.
