Claim 12:
13. An organic light-emitting diode display substrate, comprising a driving substrate, a light-emitting layer arranged on the driving substrate, a color conversion layer arranged on the light-emitting layer, an overcoat covered on the color conversion layer and a light modulation layer, wherein the light-emitting layer is configured to emit a first color light, the light modulation layer and the color conversion layer are arranged on different light-exiting paths of the light-emitting layer, the color conversion layer is configured to convert the first color light into a second color light and a third color light, and the light modulation layer is configured to modulate an emergent direction of the first color light,
wherein the light-emitting layer comprises a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit that are periodically arranged on a driving substrate and emit the first color light, the light modulation layer comprises a first light modulation unit and a second light modulation unit that are arranged on a light-exiting path of the first light-emitting unit and modulates the emergent direction of the first color light, and the color conversion layer comprises a second color conversion unit that is arranged on a light-exiting path of the second light-emitting unit and converts the first color light into the second color light and a third color conversion unit that is arranged on a light-exiting path of the third light-emitting unit and converts the first color light into the third color light, and
wherein a distance between a surface of the overcoat near to the driving substrate, which locates at a position corresponding to the second color conversion unit and the third color conversion unit, and the driving substrate is greater than a distance between a surface of the overcoat near to the driving substrate, which locates between the second color conversion unit and the third color conversion unit, and the driving substrate.
