Abstract

A display panel includes a light-emitting substrate, a first wavelength conversion layer and a second wavelength conversion layer. The light-emitting substrate includes multiple light-emitting structures corresponding to the pixels respectively, at least one light-emitting structure includes one or more first light-emitting layers emitting a first waveband light and one or more second light-emitting layers emitting a second waveband light laminated one on another, and a wavelength of the first waveband light is smaller than a wavelength of the second waveband light. The first wavelength conversion layer has multiple first wavelength conversion patterns corresponding to the light-emitting structures, the first wavelength conversion patterns are configured to perform up-conversion on the second waveband light emitted through the second light-emitting layers. The second wavelength conversion layer has multiple second wavelength conversion patterns corresponding to the light-emitting structures.
