The present invention relates to the field of display technology, and proposes a display panel, a manufacturing method thereof, and a display device. The display panel manufacturing method includes: providing a packaging cover plate and a display substrate, and the display substrate includes a substrate and a light-emitting device layer disposed on the substrate; The first photosensitive adhesive is arranged on one side of the packaging cover to form an annular barrier, and the second photosensitive adhesive is arranged in the annular barrier, wherein the light energy of the ultraviolet rays required for initiating the first photosensitive adhesive is less than that for initiating the The light energy of ultraviolet rays required by the second photosensitive adhesive, the first photosensitive adhesive is doped with an anti-ultraviolet agent; the package cover is irradiated with ultraviolet rays to initiate the first photosensitive adhesive and the second photosensitive adhesive; the package cover and display The substrate is pressed so that the annular retaining wall is bonded to the substrate, and at the same time, the light-emitting device layer is located in the sealed space formed by the substrate, the packaging cover plate and the annular retaining wall. The manufacturing method provided by the present disclosure can realize uniform curing of the first photosensitive adhesive and the second photosensitive adhesive.
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] OLED (Organic Electroluminescent Device) display panels have attracted widespread attention due to their low power consumption, portability, high brightness, and flexibility. Since organic electroluminescent devices are sensitive to water vapor, the intrusion of water vapor may affect the service life of organic electroluminescent devices. Therefore, in OLED display panels, organic electroluminescent devices need to be encapsulated by packaging technology to isolate water and oxygen. Traditional packaging technology includes Dam&Fill packaging technology. Dam&Fill packaging technology forms a sealed space for accommodating the light emitting device layer by setting an annular barrier wall, a substrate, and a packaging cover plate, and fills the sealed space with a filling...
