Claim 13:
14. A display including a first subpixel and a second subpixel constituting a pixel, a first light-emitting element constituting the first subpixel, a second light-emitting element constituting the second subpixel, a first pixel circuit corresponding to the first subpixel, a second pixel circuit corresponding to the second subpixel, and a drive unit configured to supply a first data signal to the first pixel circuit and a second data signal to the second pixel circuit,
wherein each of the first light-emitting element and the second light-emitting element has element characteristics having, in a relationship between luminance and current density, a first region in which a luminance forms a downward convex shape, a second region in which the luminance forms an upward convex shape and the luminance is higher than the luminance of the first region, and an inflection point present at a boundary between the first region and the second region,
the first data signal is configured to cause a current of a first current density to flow through the first light-emitting element and to cause the first light-emitting element to emit light at a first luminance,
the second data signal is configured to cause a current of a second current density to flow through the second light-emitting element and to cause the second light-emitting element to emit light at a second luminance, and
at some of gray scales, a gray scale value of the first data signal is smaller than a gray scale value of the second data signal.
