Abstract

The invention discloses a display panel and a display device. The display panel comprises: an array substrate, a light-emitting functional layer positioned on the array substrate, and a packaging structure covering the light-emitting function layer, wherein the packaging structure comprises a first inorganic layer tightly combined with the light-emitting function layer, and the first inorganic layer at least comprises a coating sub-layer used for coating particles on the surface of the light-emitting function layer. The light-emitting device is especially sensitive to water and oxygen in the air; particles or defects can be formed in the evaporation process of the light-emitting device. Water and oxygen invasion is caused by particles and defects; therefore, the failure of the light-emitting device can be caused by long-time exposure in the air; according to the display panel, the problems that the service life of the device is influenced due to the fact that the first inorganic layeris coated with the coating sub-layer are solved, the coating sub-layer of the packaging structure has good particle coating capacity and certain water-oxygen blocking capacity, water-oxygen invasion caused by the existence of particles of the first inorganic layer can be well prevented, packaging failure is caused, and then the service life of the display panel is prolonged.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] At present, organic electroluminescent display panels, also known as organic electroluminescent organic diode (OLED, Organic Light-Emitting Diode) display panels are increasingly widely used, and are more and more popular in the market because of their self-luminescence and flexibility. However, OLED displays Panels are very sensitive to moisture and oxygen. If water vapor and oxygen enter the interior of the display panel, it may cause adverse effects such as black spots, pinholes, and chemical reactions of organic materials, thereby affecting the service life and display effect of the display panel. Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a display panel and a display device, which can achieve a good packaging effect and ensure the serv...
