Abstract
A display substrate, a method for manufacturing the display substrate, a fingerprint recognition device and a display device are provided. The display substrate includes a base substrate, a black matrix sensor provided on the base substrate and a plurality of functional sensors which are spaced apart from each other, the black matrix sensor blocks at least visible light and includes a plurality of first extension portions and a plurality of second extension portions, and the first extension portions intersect the second extension portions to form a plurality of hollow regions. Orthographic projections of the functional sensors on the black matrix sensor are within the region where the black matrix sensor is located.
