Abstract
Provided are a display substrate, a manufacturing method thereof, a display device. The display substrate includes sub-pixel units on a base layer, each sub-pixel unit includes a light propagation unit including a first medium structure and a second medium structure, orthographic projections of the first medium structure and the light emitting unit on the base layer are at least partially overlapped, the second medium structure contacts at least one side of the first medium structure. The first medium structure has a refractive index larger than that of the second medium structure. A first included angle between a diagonal line and a bottom side of a first cross section of the first medium structure is equal to a total reflection angle at a contact surface between the first medium structure and the second medium structure. The first included angle is smaller than or equal to a preset angle.
