Display panel and display device

Abstract

The present invention relates to a display panel. The display panel comprises a substrate, a planarization layer, a light-emitting element and a package structure. The substrate has a display area anda non-display area; the planarization layer is disposed on the substrate to form a planarization surface; the light-emitting element is disposed on the planarization layer; the package structure is disposed on the light-emitting element and the planarization layer; the package structure includes a plurality of inorganic encapsulation film layers; the planarization layer includes a central portioncovering the display area and is extended to the peripheral portion of the non-display area; and the inorganic encapsulation film layers are configured to be in contact with the peripheral portion ofthe planarization layer at the non-display area. The planarization layer has a certain flexibility, can have an effect on releasing of stress and can facilitate reduction of the stress of the inorganic encapsulation film layers of the package structure at the package boundary so as to effectively prevent the inorganic encapsulation film layers from generating cracks, improve the package reliability of the package structure and improve the anti-bending performance of the display panel. The present invention further provides a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of technologies such as big data, cloud computing and mobile Internet, human beings have entered the era of intelligence, including smart mobile communication terminals, wearable devices and artificial intelligence and other smart devices, which have become an indispensable part of people's work and life. As an important window for human-computer interaction in the era of intelligence, display panels are also undergoing major changes. Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has the advantages of thin thickness, self-luminous performance, low power consumption, and good flexibility. Flat panel display device. [0003] Since the organic luminescent material in the OLED display panel is very sensitive to external environments such as water and o...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to provide a display panel and a display device that improve the above-mentioned problems in view of the problem that cracks are easily generated at the boundary of the packaging structure during the bending / curling process of the display panel, resulting in the intrusion of water and oxygen.
