The embodiment of the invention discloses a display panel, a display panel preparation method and a display device. The display panel comprises: a substrate; a first conductive layer located in a non-display area on one side of the substrate, and connected with the pixel electrode of a display area; a first photoresist layer, wherein the first photoresist layer and the first conductive layer are located on the same side of the substrate, an opening is formed in the first photoresist layer, and the opening exposes a part of the first conductive layer; a second conductive layer in contact with the first conductive layer exposed by the opening; and a packaging layer positioned on one side, far away from the substrate, of the second conductive layer. According to the technical scheme provided by the embodiment of the invention, the second conductive layer is in contact with the first conductive layer exposed by the opening; and the second metal layer is formed along the extension direction of the opening to form the auxiliary electrode with a lead wire function, and an acid etching process in the prior art is replaced, so that the problem of lateral erosion of the auxiliary electrode is solved, and the reliability of the device is ensured.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a method for manufacturing the display panel, and a display device. Background technique [0002] In the non-display area of the OLED (Organic Light-Emitting Diode) display panel, the conductive layer is usually covered with a metal layer with good conductivity, which acts as an auxiliary electrode, which can reduce the film resistance, thereby reducing power consumption. [0003] However, the surface of the auxiliary electrode is easily oxidized and corroded. In the prior art, the auxiliary electrode is formed by acid etching, which makes the auxiliary electrode prone to side erosion, resulting in a series of malfunctions after the auxiliary electrode falls off or a short circuit occurs between the auxiliary electrodes. phenomenon, reducing the reliability of the device.
