Abstract
A display substrate and a manufacturing method thereof, and a display device, are disclosed. The display substrate includes a base substrate and a thin film transistor (TFT) array, including a plurality of TFTs. A first electrode in each TFT includes a first portion and a second portion, a height of the second portion being greater than a height of the first portion in a direction perpendicular to the base substrate, wherein the first portion forms a groove with respect to the second portion and a wall of the groove comprises the second portion of the first electrode of a thin film transistor adjacent to the TFT. A bottom of the groove is the first pixel electrode of a light emitting element, wherein an organic light emitting functional layer is deposited in the groove on the first pixel electrode, and the second pixel electrode on the organic light emitting functional layer.
