1. A display substrate, comprising:
a backplane;
first light-emitting devices capable of emitting first color light and second light-emitting devices capable of emitting second color light that are disposed on the backplane;
a low-refractive-index intercalation layer disposed at a side, away from the backplane, of the first light-emitting devices and the second light-emitting devices; and
an encapsulation layer including a first inorganic barrier layer, a first organic barrier layer and a second inorganic barrier layer that are sequentially stacked on a side of the low-refractive-index intercalation layer away from the backplane;
wherein a refractive index of the low-refractive-index intercalation layer is less than a refractive index of the first inorganic barrier layer; and in a direction perpendicular to the backplane, a transmittance of the low-refractive-index intercalation layer to the first color light is less than a transmittance of the low-refractive-index intercalation layer to the second color light.
