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.
Claims12
An organic EL display unit comprising:
- a first organic EL device and a second organic EL device, the first organic EL device including a first light-emitting layer that emits first color light, and the second organic EL device including a second light-emitting layer that emits second color light of a shorter wavelength than the first color light,
- wherein the first light-emitting layer includes, as a host material, a first 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 that emits the first color light, and
- wherein the second light-emitting layer includes the low-molecular-weight material as the dopant of the first light-emitting layer near an interface with one of other layers above and below the second light-emitting layer.
An electronic apparatus provided with an organic EL display unit, the organic EL display unit comprising:
- a first organic EL device and a second organic EL device, the first organic EL device including a first light-emitting layer that emits first color light, and the second organic EL device including a second light-emitting layer that emits second color light of a shorter wavelength than the first color light,
- wherein the first light-emitting layer includes, as a host material, a first 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 that emits the first color light, and
- wherein the second light-emitting layer includes the low-molecular-weight material as the dopant of the first light-emitting layer near an interface with one of other layers above and below the second light-emitting layer.
An organic EL display unit comprising:
- a first organic EL device including a first light-emitting layer that emits red light;
- and
- a second organic EL device including a second light-emitting layer that emits green light,
- wherein the first light-emitting layer includes, as a host material, a first polymer material that emits green light, and includes, as a dopant, a second polymer material that emits red light, and
- wherein the second light-emitting layer includes the second polymer material as the dopant of the first light-emitting layer near an interface with one of other layers above and below the second light-emitting layer.
