Description

Display panel and display device Technical Field The present application relates to the field of display technologies, and in particular, to a display panel and a display device. Background With the continuous maturation of display technology, consumers have also increased demands for display panels, and manufacturers are required to make larger-sized display panels. In the related art, a plurality of small-sized display panels are commonly spliced to form a borderless spliced screen with an oversized size, so as to meet the requirements of consumers on the large display panels. In the related art, when the display panel of the borderless spliced screen is manufactured, a transparent film layer is formed by printing on one side of the shading layer, which is away from the array substrate, so as to cover one side surface of the light emitting device of the display panel, which is away from the substrate, and package and protect the light emitting device, and prevent external vapor from corroding the light emitting device. However, the packaging mode of the light emitting device is complex, time and labor are wasted, and the manufacturing efficiency of the display panel is affected. Disclosure of Invention Accordingly, it is necessary to provide a display panel and a display device aiming at the problems that the packaging mode of the light emitting device of the current display panel is complex and the manufacturing efficiency of the display panel is affected. A display panel, comprising: an array substrate; The light-emitting device is positioned on one side of the array substrate; the shading layer is positioned on the same side of the array substrate as the light emitting devices and at least partially positioned on the periphery of the light emitting devices; The composite film layer is positioned on one side of the light emitting device, which is away from the array substrate, and the composite film layer comprises a filling layer and a decorative layer which are overlapped along the thickness direction of the array substrate. The application also provides a display device comprising the display panel. According to the display panel and the display device, the composite film layer is arranged on the side, away from the array substrate, of the light-emitting device and the shading layer, so that the composite film layer can encapsulate and protect the light-emitting device, and the risk of corrosion of external water vapor to the light-emitting device is reduced. The composite film layer is formed by stacking the filling layer and the decorative layer, so that the filling layer and the decorative layer can be stacked to prepare a successful composite film layer before the display panel is processed, and then, the prepared composite film layer is pressed on one side, away from the array substrate, of the light emitting device and the shading layer in the process of manufacturing the display panel, so that the light emitting device can be protected, and the rapid packaging of the light emitting device is realized. As described above, since the composite film layer can be prepared in advance, the light emitting device is packaged using the composite film layer, which is simpler, more time-saving and labor-saving than printing the transparent packaging layer on the surface of the light emitting device, and more conducive to improving the manufacturing efficiency of the display panel. As can be seen from the above, the display panel and the display device according to the embodiments can simplify the package of the light emitting device, and make the package of the light emitting device more time-saving and labor-saving.
