1. A display device comprising:
a display panel including:
a first subpixel including a first light-emitting element, and
a second subpixel adjacent to the first subpixel and including a second light-emitting element;
a circuit unit configured to calculate a degradation amount of the first light-emitting element in accordance with a light-emission state of the second light-emitting element, and to calculate a compensation value of the first light-emitting element in accordance with the calculated degradation amount of the first light-emitting element;
a first region extending from a center of the first subpixel; and
a second region surrounding the first region,
wherein the circuit unit is further configured to:
set a weighting coefficient, based on a positional relationship between the first subpixel and a light-emitting element at least partially included in the first region, greater than a weighting coefficient that is determined based on a positional relationship between the first subpixel and a light-emitting element included either in the second region alone or in both the second region and a region out of the second region, and
calculate the degradation amount of the first light-emitting element.
