Classification: CPC G | IPC C  G  H

Claim 0:
1. A display device comprising:
a pixel including a light emitting unit, wherein
the light emitting unit includes at least one sub element group,
the at least one sub element group includes a first sub element group and a second sub element group electrically connected in series, and
each of the first and second sub element groups includes a plurality of light emitting elements electrically connected in parallel;

a data driver that supplies a data voltage to the pixel; and
a luminance corrector that corrects image data and generates compensation data corresponding to the data voltage,
wherein a number of the light emitting elements of each of the first and second sub element groups is obtained by at least one of optical imaging, thermal imaging, and pixel sensing, and
the luminance corrector extracts a deterioration value of the at least one sub element group and calculates a luminance value of the at least one sub element group according to a number of the light emitting elements included in the at least one sub element group using a look up table that stores a deterioration value for each number of the light emitting elements.
