Abstract

The present application provides a light-emitting component and a method for manufacturing the same, a display substrate, and a display device. The light-emitting component comprises: an anode layer stacked on one side of a base, a first functional layer group including a plurality of functional layers, an organic light-emitting layer, a second functional layer group including a plurality of functional layers, and a cathode layer; the first functional layer group comprises a hole injection delaying layer close to the organic light-emitting layer, and the hole injection delaying layer is used for reducing a hole transport rate; and/or the second functional layer group comprises an electron injection delaying layer close to the organic light-emitting layer, and the electron injection delaying layer is used for reducing an electron transport rate.
