Degradation compensation device and display device including the same

A display device comprising:

• a display unit including a first pixel disposed in a first region and a second pixel disposed in a second region different from the first region;
• a degradation compensator which generates a first compensated grayscale value by compensating a first grayscale value for the first pixel based on a first degradation curve and generates a second compensated grayscale value by compensating a second grayscale value for the second pixel based on a second degradation curve, wherein the first degradation curve defines a luminance reduction rate according to a first accumulated usage time of the first pixel, and the second degradation curve defines a luminance reduction rate according to a second accumulated usage time of the second pixel;
• and
• a data driver which generates a first data signal based on the first compensated grayscale value, supplies the first data signal to the first pixel, generates a second data signal based on the second compensated grayscale value, and supplies the second data signal to the second pixel,
• wherein a light transmittance of the second region is greater than a light transmittance of the first region.
