1. A display device comprising:
a first subpixel including a quantum dot light-emitting layer configured to emit light of a first color;
a second subpixel including a quantum dot light-emitting layer configured to emit light of a second color different from the light of the first color;
a third subpixel including a quantum dot light-emitting layer configured to emit light of a third color different from the light of the first color and the light of the second color; and
a data processing circuit configured to receive first input data corresponding to the first subpixel, second input data corresponding to the second subpixel, and third input data corresponding to the third subpixel,
wherein the data processing circuit is further configured to generate:
first output data corresponding to a first data voltage supplied to the first subpixel by using the first input data, the second input data, and the third input data,
second output data corresponding to a second data voltage supplied to the second subpixel by using the first input data, the second input data, and the third input data, and
third output data corresponding to a third data voltage supplied to the third subpixel by using the first input data, the second input data, and the third input data, and
wherein a wavelength range of the light of the first color is closer to a long wavelength side than a wavelength range of the light of the second color, and a wavelength range of the light of the second color is closer to the long wavelength side than a wavelength range of the light of the third color,
a gray scale of the second output data is TGc and a gray scale of the third output data is TBc in a case that a gray scale of the first input data is Tc, where Tc is lower than a center of a full gray scale, a gray scale of the second input data is Tm, and a gray scale of the third input data is Tn,
the gray scale of the second output data is TGd and the gray scale of the third output data is TBd in a case that the gray scale of the first input data is Td, where Td is higher than the center of the full gray scale, the gray scale of the second input data is Tm, and the gray scale of the third input data is Tn,
TGc<TGd, and
TBc<TBd.
