Abstract
A display device includes: a substrate including a first emission area, a second emission area, and a third emission area; a first wavelength conversion pattern overlapping the first emission area; a second wavelength conversion pattern overlapping the second emission area; and a light-transmitting pattern overlapping the third emission area, wherein the first wavelength conversion pattern includes first wavelength shifters configured to convert a first light into a second light, and first scatterers, the second wavelength conversion pattern includes second wavelength shifters configured to convert the first light into a third light, and second scatterers, and a ratio between a concentration of the first wavelength shifters and a concentration of the second wavelength shifters is 1:1.1 to 1:1.3.
