Claim 17:
18. A method of manufacturing a display panel, comprising:
preparing a first display substrate, which comprises forming a light-emitting element array on a first substrate, wherein the light-emitting element array comprises a plurality of light-emitting elements for generating and emitting a first color light; preparing a second display substrate, which comprises forming a color-conversion layer array on a second substrate, wherein the color-conversion layer array comprises a plurality of color-conversion layers which correspond to the plurality of light-emitting elements one by one, and the plurality of color-conversion layers are configured to generate other color lights under excitation of the first color light; and
aligning and assembling the first display substrate and the second display substrate such that the light-emitting element array and the color-conversion layer array are located between the first substrate and the second substrate; wherein the preparing the second display substrate further comprises, after the forming the color-conversion layer array, a step of: forming a first band-pass filtering layer on one side of the color-conversion layer array distal to the second substrate, wherein the first band-pass filtering layer comprises: a first band-pass filtering structure in contact with a first light-converging structure, the first light-converging structure is arranged on one side of the first band-pass filtering structure distal to the second substrate, the first light-converging structure is configured to converge light rays, and the first band-pass filtering structure is configured to transmit the first color light and reflect the other color lights; and/or
wherein the preparing the second display substrate further comprises, before the forming the color-conversion layer array, a step of: forming a second band-pass filtering layer on one side of the second substrate on which the color-conversion layer array is subsequently formed such that the second band-pass filtering layer comprises a second band-pass filtering structure and a second light-converging structure on one side of the second band-pass filtering structure distal to the second substrate, the second light-converging structure is configured to converge light rays, and the second band-pass filtering structure is configured to transmit the other color lights and reflect the first color light.
