1. A display panel, comprising
a light emitting element,
a color conversion region disposed on the light emitting element,
wherein the light emitting element is configured to provide the color conversion region with incident light, wherein the color conversion region includes a wavelength conversion structure comprising a base structure including partition wall, the partition wall defining a first space and a second space, a first quantum dot composite, and
a second quantum dot composite,
wherein the first quantum dot composite comprises a first matrix and a plurality of first quantum dots dispersed in the first matrix, and the second quantum dot composite comprises a second matrix and a plurality of second quantum dots dispersed in the second matrix,
wherein a height of the partition wall is greater than or equal to about 5 micrometers and less than or equal to about 50 micrometers,
wherein the first space and the second space include a first open face and a second open face, respectively, and
wherein the first quantum dot composite and the second quantum dot composite are disposed in the first space and the second space, respectively,
wherein the first quantum dot composite provides a first top surface facing the first open face; or
wherein the second quantum dot composite provides a second top surface facing the second open face.
