    摘要： An electroluminescent display panel and a manufacturing method thereof, and a display device. Each of a plurality of pixel units (123) included in the electroluminescent display panel includes a first sub-pixel (100), a second sub-pixel (200) and a third sub-pixel (300), respectively, each of the sub-pixels (100, 200, 300) includes a first electrode (110, 210, 310), and a light-emitting layer (120, 220, 320), respectively, a first color light (101) emitted by the first sub-pixel (100) forms a first standing wave (102), a second color light (201) emitted by the second sub-pixel (200) forms a second standing wave (202), a third color light (301) emitted by the third sub-pixel (300) forms a third standing wave (302), a wavelength of the first color light (101) is greater than a wavelength of the second color light (201) and a wavelength of the third color light (301), taking a planar surface of the first electrode (110, 210, 310) facing the light-emitting layer (120, 220, 320) as a reference plane, the light-emitting layer (120) of the first sub-pixel (100) is on a first anti-node (1021) of the first standing wave (102), the light-emitting layer (220) of the second sub-pixel (200) is on a second anti-node (2022) of the second standing wave (202), and the light-emitting layer (320) of the third sub-pixel (300) is on a second anti-node (3022) of the third standing wave (320). The printing process window in the electroluminescent display panel can be greatly increased, thereby improving the performance of the display device.
