Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, and belongs to the technical field of display. The display panel comprises a substrate, and a pixel defining layer, a light emitting device and an auxiliary electrode layer which are located on the substrate. According to the invention, when the light-emitting layer in the light-emitting device is formedon the auxiliary electrode, the light-emitting layer has a broken line phenomenon in the area where the auxiliary electrode is located, and the side wall of the auxiliary electrode is provided with the groove, so that when the cathode layer is formed on the light-emitting layer, the cathode layer can extend into the groove in the side wall of the auxiliary electrode and is in contact with the groove. In this way, effective lap joint between the cathode layer and the auxiliary electrode layer can be achieved, and the display effect of the display panel is good.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] The current organic electroluminescent (English: Organic Light-Emitting Diode abbreviation: OLED) display panel usually includes an anode layer, an organic light-emitting layer and a cathode layer, which can be divided into bottom-emitting OLED display panels and top-emitting OLEDs according to different light-emitting surfaces. There are two types of display panels. Since the top emission OLED display panel can obtain a larger aperture ratio, it has become a research hotspot in recent years. [0003] Top-emission OLED display panels require a thin and transparent cathode layer and an anode layer capable of light reflection to increase light transmittance, and the thin and transparent cathode layer generally has a high resistance value and a serious voltage drop (IRdrop...
