Abstract
(EN) A display device (10) and a preparation method therefor. The display device (10) comprises a substrate (100), a light shielding layer (200), and a color film layer (300); an upper surface (101) of the substrate (100) has a concave-convex structure (110); the light shielding layer (200) is provided on the substrate (100); and the color film layer (300) is provided on the light shielding layer (200). The concave-convex structure (110) is provided on the substrate (100), so that the area of contact between the light shielding layer (200) and the substrate (100) is increased, the wettability between the light shielding layer (200) and the substrate (100) is improved, and stripping of the light shielding layer (200) is avoided, thus the performance of the display device (10) is improved.
(FR) L'invention concerne un dispositif d'affichage (10) et son procédé de préparation. Le dispositif d'affichage (10) comprend un substrat (100), une couche de protection contre la lumière (200), et une couche de film coloré (300) ; une surface supérieure (101) du substrat (100) a une structure concave-convexe (110) ; la couche de protection contre la lumière (200) est disposée sur le substrat (100) ; et la couche de film coloré (300) est disposée sur la couche de protection contre la lumière (200). La structure concave-convexe (110) est disposée sur le substrat (100), de sorte que la zone de contact entre la couche de protection contre la lumière (200) et le substrat (100) est augmentée, la mouillabilité entre la couche de protection contre la lumière (200) et le substrat (100) est améliorée, et le décapage de la couche de protection contre la lumière (200) est évité, ainsi la performance du dispositif d'affichage (10) est améliorée.
(ZH) 一种显示装置(10)及其制备方法,显示装置(10)包括基板(100)、遮光层(200)以及彩膜层(300),基板(100)的上表面(101)具有凹凸结构(110),遮光层(200)设置于基板(100)上,彩膜层(300)设置于遮光层(200)上,通过在基板(100)上设置凹凸结构(110),进而提高遮光层(200)与基板(100)的接触面积,进而提高遮光层(200)与基板(100)之间的润湿性,进而避免了遮光层(200)的剥离,进而提高显示装置(10)的性能。
