The embodiment of the invention provides a display panel and a manufacturing method thereof, a display device, a mask strip and a mask plate, relates to the technical field of display, and aims to solve the problem that the electrical connection performance between electrodes of adjacent light-emitting devices in the display panel is poor. The display panel comprises a substrate, a first electrode layer, a pixel defining layer, an isolation structure, a plurality of light-emitting functional layers, a second electrode layer and a conductor layer. The first electrode layer comprises a plurality of first electrodes. The pixel defining layer is arranged on the side, away from the substrate, of the first electrode layer, the pixel defining layer is provided with a plurality of first openings, and one first opening exposes at least one part of one first electrode. The isolation structure is arranged between two adjacent first openings. At least one of the plurality of light-emitting functional layers is broken at the isolation structure. The conductor layer comprises a plurality of connection patterns, one connection pattern is in contact with parts, located on the two sides of the isolation structure in the first direction, in the second electrode layer, and the first direction is the arrangement direction of every two adjacent first openings.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method, a display device, a mask strip and a mask plate. Background technique [0002] In an Organic Light Emitting Diode (OLED) display panel, an electrode (such as a cathode) of each light-emitting device (ie OLED) may be connected to each other, or it may be said that the electrodes of each light-emitting device may be a continuous film layer, an electrical signal can be written into the continuous film layer to control the light emission of each light emitting device. Based on this, the conductive performance of the film layer has a great influence on the display effect of the display panel. For example, the electrical connection performance between electrodes of adjacent light emitting devices may be poor, which affects the display effect of the display panel.
