Claim 0:
1. A display panel, comprising:
a first substrate, a light-emitting element array and a color-conversion layer array, wherein the light-emitting element array is arranged on one side of the first substrate and comprises a plurality of light-emitting elements, the color-conversion layer array is located on a side of the light-emitting element array distal to the first substrate, and comprises a plurality of color-conversion layers in one-to-one correspondence with the plurality of light-emitting elements, the light-emitting elements are configured to generate and emit first color light, and the corresponding plurality of color-conversion layers are configured to generate other color lights under excitation of the first color light, wherein the display panel further comprises:
a first band-pass filtering layer located between the light-emitting element array and the color-conversion layer array, comprising: a first light-converging structure in contact with a first band-pass filtering structure, wherein the first light band-pass filtering structure is located on a 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 first color light and reflect the other color lights; and/or
a second band-pass filtering layer located on a side of the color-conversion layer array, distal to the light-emitting element array, comprising: a second light-converging structure and a second band-pass filtering structure, wherein the second light band-pass filtering structure is located on a side of the second light-converging structure distal to the first 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.
