Claim 18:
19. A method of manufacturing a display panel, comprising:
forming a light-emitting element array on a first substrate such that the light-emitting element array comprises a plurality of light-emitting elements for generating and emitting a first color light; forming a color-conversion layer array on one side of the light-emitting element array, distal to the first substrate, wherein the color-conversion layer array comprises a plurality of color-conversion layers in one-to-one correspondence with the plurality of light-emitting elements, and the plurality of color-conversion layers are configured to generate other color lights under excitation of the first color light; between the forming the light-emitting element array and the forming the color-conversion layer array, the method further comprises:
forming a first band-pass filtering layer on one side of the light-emitting element array distal to the first substrate such that the first band-pass filtering layer comprises a first light-converging structure in contact with a first band-pass filtering structure, wherein the first band-pass filtering structure is arranged on one side of the first light-converging structure distal to the first 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
after the forming the color-conversion layer array, the method further comprises forming a second band-pass filtering layer on one side of the color-conversion layer array distal to the first substrate such that the second band-pass filtering layer comprises a second light-converging structure and a second band-pass filtering structure, 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.
