The present invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes: a first base substrate, on which a plurality of pixel units distributed in an array are arranged, and each pixel unit includes at least The first groove, the second groove and the third groove, the first groove and the second groove are arranged at intervals on the first side of the first base substrate, and the third groove is arranged on the first side of the first base substrate two sides, and the third groove is arranged corresponding to the gap between the first groove and the second groove; the first light-emitting layer is arranged in the first groove; the second light-emitting layer is arranged in the second groove; a third light emitting layer disposed in the third groove; and a first electrode layer disposed on the first side of the first base substrate, the first electrode layer covering the first light emitting layer and the second light emitting layer. It can solve the problem of poor color mixing caused by the small pixel pitch of high-resolution display products, and the pixel size and pitch can be further reduced to improve the resolution of display products.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices have become a highly competitive and promising display device due to a series of advantages such as self-luminescence, fast response speed, high brightness, full viewing angle, and flexible display. . [0003] The OLED display device includes an anode, an organic light-emitting layer and a cathode that are sequentially stacked on a substrate. When a voltage is applied to the anode and the cathode, the organic light-emitting layer emits light. At present, the organic light-emitting layer of the OLED display device is generally fabricated by a vacuum evaporation method. Generally, a mode in which sub-pixels of three colors of R, G, and B are arranged in parallel is adopted. When making such an OLED device, a hi...
