1. A display device using a light-emitting element, the display device comprising:
a plurality of segmented first electrodes;
a second electrode being a common electrode disposed above the first electrodes; and
a plurality of subpixels, each of the plurality of subpixels being disposed between and electrically connected to a respective one of the first electrodes and the second electrode to constitute an individual pixel,
wherein the plurality of subpixels comprise:
a first subpixel configured to emit light of a first color and comprising an organic light-emitting diode;
a second subpixel configured to emit light of a second color and comprising an organic light-emitting diode;
a third subpixel configured to emit light of a third color and comprising an inorganic light-emitting diode; and
a fourth subpixel comprising an organic light-emitting diode configured to emit light in which the light of the first color to the light of the third color are mixed.
