1. A display device comprising:
a substrate comprising 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 comprises first wavelength shifters configured to convert a first light into a second light, and first scatterers,
the second wavelength conversion pattern comprises 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 in the first wavelength conversion pattern and a concentration of the second wavelength shifters in the second wavelength conversion pattern is 1:1.1 to 1:1.3.
