Abstract: According to an aspect, a display device includes: a substrate; and a plurality of pixels provided on the substrate. Each of the pixels includes a red light emitting element and a first green light emitting element. When the first green light emitting element and the red light emitting element are turned on simultaneously, an emission intensity of the first green light emitting element is lower than an emission intensity of the red light emitting element, and a half width of a spectrum of light output from the first green light emitting element is greater than a half width of a spectrum of light output from the red light emitting element.
