Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a display area and a non-display area adjacent to the display area. The manufacturing method of the display panel comprises the following steps: providing a substrate; a signal terminal located in the non-display area is formed on the substrate; forming a light-emitting layer located in the display area on the substrate; an electronic layer and a cathode layer are sequentially formed on the side, away from the substrate, of the light-emitting layer through a mask, the electronic layer at least covers the display area, the cathode layer covers the electronic layer and extends to the non-display area to be in lap joint with the signal terminal, and the electronic layer comprises an electron injection layer and / or an electron transmission layer. According to the invention, the preparation of the electronic layer and the cathode layer is completed through the mask plate, so that the process flow can be simplified and the process cost can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic electroluminescence (Organic Light-Emitting Diode, OLED) display panels have become the most competitive and potential competitors in future display technology due to their excellent characteristics such as high contrast ratio, wide color gamut, fast response speed, and flexibility. . [0003] At present, OLED display panels are generally prepared by vacuum evaporation, and its strict process requirements and high cost limit the large-scale popularization and application of this technology in larger-sized products. The inkjet printing technology can be carried out at normal temperature and pressure before, and the red, green and blue pixel arrays can be quickly and continuously prepared on a large-size glass substrate, which creates conditions for the manufa...
