Abstract
The invention discloses a display panel, a manufacturing method and a display device. The display panel includes: a substrate having a display area and a non-display area; a planarization layer, covering the display area and the non-display area of the substrate; an organic light-emitting element, located in the display area and located on the side, away from the substrate, of the planarization layer; a packaging structure, wrapping the organic light-emitting element and comprising a first inorganic layer, an organic layer and a second inorganic layer which are sequentially arranged in a stacked mode. The first inorganic layer and the second inorganic layer extend into the non-display area, the first inorganic layer is arranged close to the planarization layer, and the display panel meetsat least one of the following conditions that the display panel comprises a third inorganic layer, located in the non-display area and located between the planarization layer and the first inorganic layer; the portion, located in the non-display area, of the planarization layer is provided with a groove, and the groove is filled with a tough water-blocking oxygen material. Therefore, the problem that the lateral packaging effect is poor can be effectively relieved, the packaging effect is improved, the service life of the display panel is prolonged, and meanwhile the optical effect of the display area is guaranteed.
Description
technical field [0001] The present invention relates to the field of display technology, in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting display devices (OLEDs) are increasingly favored by users due to their advantages of thinness, high brightness, low power consumption, fast response, high definition, good flexibility, and high luminous efficiency. With the development of demand for display devices, the quality and lifespan requirements of OLED devices are becoming more and more stringent, and thus the packaging performance requirements of OLED devices are also becoming more and more stringent. At present, the encapsulation structure is generally formed by thin film encapsulation to prevent water vapor and oxygen from penetrating into the display device. [0003] However, current organic light emitting display devices still need to be improved. Contents of the invention [0004...
