Abstract: Provided are a coating method, a display substrate and a manufacturing method thereof, and a display device. The coating method includes: forming a micro-fluid channel on a first surface of a first substrate, wherein the first surface is a surface to be coated of the first substrate, and a sidewall of the micro-fluid channel is the first surface of the first substrate; immersing one end of the micro-fluid channel into ink, to enable the ink to fill the micro-fluid channel; and drying the ink filling the micro-fluid channel to form a thin film on the first surface of the first substrate. The present disclosure can help implement uniform film formation of a quantum dot light-emitting layer at a high resolution, reduce the process difficulty of a high-resolution product and improve the device performance and the display performance.
