Claim 11:
12. The driving method of the display according to claim 7,
wherein a size of the second subpixel is greater than a size of the first subpixel,
a film thickness of an electron transport layer provided at the first light-emitting element is greater than a film thickness of an electron transport layer provided at the second light-emitting element,
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 the luminances included in the first region,
the luminance of the first light-emitting element is greater than 0 and equal to or less than half the luminance of the inflection point in the element characteristics of the first light-emitting element, and
the luminance of the second light-emitting element is greater than 0 and equal to or less than half the luminance of the inflection point 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 luminance of the second light-emitting element, in the element characteristics of the second light-emitting element, and
when
the luminance of the first light-emitting element is greater than half the luminance of the inflection point in the element characteristics of the first light-emitting element and less than the luminance of the inflection point in the element characteristics of the first light-emitting element, and
the luminance of the second light-emitting element is greater than half the luminance of the inflection point in the element characteristics of the second light-emitting element and less than the luminance of the inflection point in the element characteristics of the second light-emitting element,
the first current density is a current density of the inflection point in the element characteristics of the first light-emitting element, and
the second current density is a current density corresponding to a luminance obtained by subtracting the luminance of the inflection point in the element characteristics of the second light-emitting element from a luminance twice as large as the desired luminance in the element characteristics of the second light-emitting element.
