1. A display device, comprising:
a plurality of sub-pixels disposed on a substrate;
a storage capacitor disposed in each of the plurality of sub-pixels;
a buffer layer disposed on the storage capacitor in each of the plurality of sub-pixels;
a transistor disposed on the buffer layer in each of the plurality of sub-pixels; and
a light emitting element disposed on the transistor in each the plurality of sub-pixels,
wherein the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, and a third sub-pixel, each of the first, second and third sub-pixels being configured to emit a different color of light,
wherein at least one of the plurality of sub-pixels includes a metal layer disposed below the transistor,
wherein the metal layer is connected to one electrode of the storage capacitor,
wherein the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a blue sub-pixel,
wherein the transistor is a driving transistor for driving the light emitting element, and
wherein a driving transistor of the third sub-pixel has a lower S-factor than that of a driving transistor of the first sub-pixel and the second sub-pixel.
