Abstract

The embodiment of the invention provides a display panel and a manufacturing method thereof, and a display device, and related to the field of display technology, which are used to solve the problem that the encapsulation layer in the display panel in the prior art is easy to peel off. The display panel includes a display area and a non-display area surrounding the display area; the display area includes a plurality of light emitting units; each of the light emitting units includes a first electrode, a light emitting layer and a second electrode which are arranged in a stack; the non-display area includes a metal layer and an inorganic layer, which contact each other, wherein the metal layer is electrically connected to the second electrodes located in the display region, and the metal layer includes an opening, the opening is filled with an organic layer, and the organic layer is in contact with the metal layer and the inorganic layer.

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 Diode (OLED) display panels are widely used in the field of display technology due to their many advantages such as active light emission, high contrast, no viewing angle limitation, and flexible display. [0003] At present, in order to improve the water and oxygen resistance characteristics of each OLED device in a flexible OLED display panel, a thin film encapsulation (Thin Film Encapsulation, hereinafter referred to as TFE) method is usually used, that is, the encapsulation layer is set as an inorganic layer and an organic layer stacked. To package the OLED display panel. However, in the design of the existing OLED display panel, the inorganic layer in the encapsulation layer is in contact with some metal wiring layers used for signal trans...
