Claim 10:
11. The driving method of the display according to claim 7,
wherein when, in the element characteristics of the first light-emitting element and the element characteristics of the second light-emitting element,
a second tangential line is present in the second region, the second tangential line having an inclination similar to an inclination of a first tangential line obtained when the luminance is 0 on a curved line indicating a relationship between the current density and the luminance, and
a luminance corresponding to a point at which the curved line meets the second tangential line is defined as a luminance (LD) of a specific point,
a luminance of the inflection point in the element characteristics of the first light-emitting element is less than half the luminance of the specific point (LD/2) in the element characteristics of the first light-emitting element, and
a luminance of the inflection point in the element characteristics of the second light-emitting element is less than half the luminance of the specific point (LD/2) in the element characteristics of the second light-emitting element, and
when, in the element characteristics of each of the first light-emitting element and the second light-emitting element,
the luminance of the first light-emitting element and the luminance of the second light-emitting element are luminances included in the second region,
the luminance of the first light-emitting element is greater than the luminance of the inflection point in the element characteristics of the first light-emitting element and equal to or less than half the luminance of the specific point (LD/2) in the element characteristics of the first light-emitting element, and
the luminance of the second light-emitting element is greater than the luminance of the inflection point in the element characteristics of the second light-emitting element and equal to or less than half the luminance of the specific point (LD/2) in the element characteristics of the second light-emitting element,
the first current density is 0, and
the second current density is a current density corresponding to a luminance twice as large as the desired luminance, in the element characteristics of the second light-emitting element.
