Abstract

The invention discloses a display panel, a display panel preparation method and a display device. The display panel comprises: a substrate; a plurality of functional film layers stacked on one side of the substrate, wherein at least one functional film layer comprises a main body part arranged in a first area and an extension part extending to a retaining wall setting area; and a packaging layer comprising a first packaging layer, wherein the first packaging layer comprises a first packaging section and a second packaging section, the first packaging section covers the sides, away from the substrate, of the multiple functional film layers, the second packaging section comprises a first sub-packaging part covering the sides, away from the substrate, of the extension parts and a second sub-packaging part located in the peripheral area, a segment difference exists between the first sub-packaging part and the second sub-packaging part which are separated by a film layer, and the retaining wall structure comprises the extension part, the first sub-packaging part and the film layer which are stacked. According to the invention, while a narrow frame is ensured, cutting cracks are effectively prevented from extending to the display area of the display panel through the second sub-packaging part, so that the packaging reliability of the display panel is ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel, a method for preparing the display panel and a display device. Background technique [0002] At present, the development of narrow bezels of display devices has become a market trend, and it is also one of the factors for the competitiveness of major mobile phone manufacturers. Narrow bezels bring a higher screen-to-body ratio and improve consumer experience. However, due to the limitations of the manufacturing capacity of the mask plate and the alignment accuracy of the equipment, it is not conducive to the realization of a narrow frame of the display device. [0003] Therefore, there is an urgent need for a new display panel, a method for manufacturing the display panel, and a display device. Contents of the invention [0004] Embodiments of the present invention provide a display panel, a method for preparing a display panel, and a d...
