Abstract

The invention discloses a display substrate, a manufacturing method thereof, and a display device, belonging to the technical field of display. The display substrate includes: a base substrate, on which a first light-emitting unit is arranged, and the first light-emitting unit includes: a first selective reflective transmission layer, an anode layer, a first organic light-emitting layer, a cathode layer and a reflective layer stacked in sequence ; Wherein, the first organic light-emitting layer can emit colored light under the action of the anode layer and the cathode layer, and the first selective reflective transmission layer and the reflective layer can reflect the colored light, so that the colored light can be reflected in the first selective Vibration between the reflective transmissive layer and the reflective layer, through the first selective reflective transmissive layer emitted from the base substrate, the present invention solves the problem of low light extraction efficiency of the display substrate and the display device, and improves the efficiency of the display substrate and the display device The effect of light efficiency. The invention is used for display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display device is a display device with an autonomous light emitting function. Because it does not require a backlight, and has the advantages of high contrast, thin thickness, wide viewing angle, fast response, high and low temperature resistance, etc., it has broad prospects in the display industry. [0003] OLED display devices can generally include a display substrate. In the prior art, the display substrate includes a base substrate, and three light-emitting units stacked in sequence are arranged on the base substrate. For example, the three light-emitting units include: a red light unit, Green light unit and blue light unit, each light-emitting unit includes: a cathode layer, an...
