10. A display device comprising:
a pixel unit including pixels connected to scan lines and data lines;
a data driver configured to supply a data signal to the data lines;
a gamma voltage supplier configured to supply a gamma voltage to the data driver corresponding to a gamma value;
a timing controller including a storage unit configured to store the gamma value and a look-up table; and
a temperature sensor configured to sense a temperature of the pixel unit,
wherein a plurality of dimming levels, a plurality of grayscales included in each of the plurality of dimming levels, and gamma value setting information corresponding to at least two different temperatures in each of the plurality of grayscales are stored in the look-up table, and
wherein the gamma value setting information corresponds to a target luminance and a target color coordinate of the pixel unit which correspond to the different temperatures, or the gamma value corresponding to the different temperatures.
