Display devices

Abstract

A display device is provided. The display device includes a substrate, and a first sub-pixel and a second sub-pixel disposed on the substrate, wherein the first sub-pixel and the second sub-pixel respectively correspond to two different colors. The first sub-pixel includes a first light-emitting element and a first wavelength conversion layer adjacent to the first light-emitting element, wherein a light emitted from the first light-emitting element passes through the first wavelength conversion layer. The second sub-pixel includes a second light-emitting element and a second wavelength conversion layer adjacent to the second light-emitting element, wherein a light emitted from the second light-emitting element passes through the second wavelength conversion layer. An area of the first wavelength conversion layer and an area of the second wavelength conversion layer are different.
