Abstract: A display device includes a pixel including a plurality of sub-pixels. Each of the plurality of sub-pixels includes: a light-emission region; and a non-light-emission region other than the light-emission region. The light-emission region includes one or more effective light-emitting parts in which a first electrode, a light emitting layer, and a second electrode are stacked in order, and a light guide provided on side of the one or more effective light-emitting parts on which light is extracted.

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.
