Abstract

The invention provides a display panel, a display device and a manufacturing method of the display panel. The display panel comprises a substrate; an array layer which is arranged on one side of the substrate; a luminescence functional layer which is arranged on one side away from the substrate of the array layer and comprises an anode layer, an organic light-emitting layer and a cathode layer which are arranged along the direction away from the substrate; and a thin film packaging layer which is arranged on one side away from the array layer of the luminescence functional layer and completelycovers the luminescence functional layer and comprises a first inorganic packaging layer, a first organic packaging layer and a second inorganic packaging layer which are arranged along the directionaway from the substrate, wherein the edges of the orthographic projection of the cathode layer, the first inorganic packaging layer and the first organic packaging layer on the display panel are overlapped, and the second inorganic packaging layer covers the luminescence functional layer, the first inorganic packaging layer and the first organic packaging layer. According to the display panel, the manufacturing process can be simplified and the accuracy of the cathode patterning technology can be enhanced.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a display device including the display panel, and a manufacturing method of the display panel. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is also becoming mature. Existing display panels mainly include organic light emitting diode (Organic Light Emitting Diode, OLED) display panels, liquid crystal display panels (Liquid Crystal Display, LCD). OLED display panels are widely used in the field of display because of their advantages such as self-luminescence, low power consumption, fast response speed, and wide viewing angle. [0003] However, OLED display panels are very sensitive to oxygen and moisture. If oxygen and water vapor penetrate into the OLED display panel, it may cause adverse effects such as black spots, pinholes, and chemical reactions of organic materials, thereby affect...
