Abstract
An organic EL display unit includes a first organic EL device including a first light-emitting layer that emits first color light and a second organic EL device including a second light-emitting layer that emits second color light of a shorter wavelength than the first color light. The first light-emitting layer includes, as a host material, a polymer material that does not emit the first color light or does not mainly emit the first color light, and includes, as a dopant, a low-molecular-weight material or a polymer material that emits the first color light.
