Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, and belongs to the technical field of display. The display panel includes: a substrate; a bottom electrode layer arranged on one side of the substrate; a light-emitting layer, which comprises a plurality of first light-emitting functional layers and a plurality of second light-emitting functional layers which are alternately arranged in the horizontal direction of the bottom electrode layer, and any one of the first light-emitting functional layers and the second light-emitting functional layers is arranged to be of an inverted structure; and a top electrode layer, which is arranged on one side, far away from the bottom electrode layer, of the light-emitting layer. The display panel provided by the invention can be driven by using alternating current, so that the service life is longer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] An organic light emitting diode (OLED) display has the advantages of self-illumination, simple structure, thinness, fast response, wide viewing angle, low power consumption, and flexible display. Quantum dot light emitting diodes (Quantum Dot Light Emitting Diodes, QLED) have the characteristics of high color purity, lightness, thinness and flexibility, and are suitable for large-area coating process. , so there are also potential advantages in the field of lighting. [0003] However, the current QLED display panels and OLED display panels are driven by DC power supply, and the service life needs to be improved. Contents of the invention [0004] The main purpose of the present invention is to provide a display panel and its manufacturing method and display device, ai...
