Abstract
The invention discloses a display panel, a manufacturing method of the display panel and a display device, and belongs to the technical field of display. Before the display panel is detected, a protective film is formed on a packaging layer of the display panel; and after detection is completed, the protective film on the display panel is stripped, wherein the protective film is respectively bonded with the packaging layer and the auxiliary retaining wall. The auxiliary retaining wall is arranged in the non-display area of the display panel, and the height of the auxiliary retaining wall is larger than the distance between the side, away from the substrate, of the packaging layer and the substrate. In the process of stripping the protective film bonded with the packaging layer and the auxiliary retaining wall in the display panel, the protective film is firstly separated from the auxiliary retaining wall and then separated from the packaging layer, so that in the stripping process, the acting force between the protective film and the auxiliary retaining wall is larger than the acting force between the protective film and the packaging layer, the probability that the packaging layer falls off in the stripping process of the protective film is reduced, and the product yield of the display panel is improved.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a manufacturing method of the display panel, and a display device. Background technique [0002] Organic Light-Emitting Diode (English: Organic Light-Emitting Diode; referred to as: OLED) is a current-type light-emitting device, because of its low power consumption, self-illumination, high color saturation, fast response, wide viewing angle and flexible It is more and more used in the field of high-performance display due to its characteristics such as customization. [0003] An OLED display panel may generally include: a light emitting device and an encapsulation layer. The encapsulation layer may include: a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer which are stacked. The encapsulation layer is used to encapsulate the light-emitting device, isolate the light-emitting device fro...
