A light source includes a light emitting element and a light conversion layer configured to convert light emitted from the light emitting element into white light; wherein the light conversion layer includes a matrix resin and a quantum dot, wherein the white light includes a red light component, a green light component, and a blue light component each having a color purity configured to display a color gamut having a concordance rate of greater than or equal to about 99.0% with an Adobe RGB color gamut of a display device, and wherein the green light component has a peak wavelength of about 525 nanometers to about 528 nanometers and a full width at half maximum of less than or equal to about 40 nanometers, and a red light component having a peak wavelength of about 625 nanometers to about 645 nanometers.
