Abstract
A light-emitting device includes an HTL including a metal chalcogenide between an anode and an EML, with an IL including an organic material at least between the HTL and the EML. A distance between the HTL and the EML in a light-emitting element that emits light in a wavelength band having the shortest light emission peak wavelength is greater than a distance between the HTL and the EML in each of the other light-emitting elements.
