LIGHT EMITTING DEVICE AND DISPLAY APPARATUS INCLUDING THE SAME

Provided is a light emitting device including a first electrode (EL1), a hole transport region (HTR) on the first electrode, a first light emitting layer (BEML1) on the hole transport region and emitting light of a first wavelength, a second light emitting layer (GEMLn) on the hole transport region and emitting light of a second wavelength different from the first wavelength, an electron transport region (ETR) on the first light emitting layer and the second light emitting layer, and a second electrode (EL2) on the electron transport region. The second light emitting layer includes a first sub-light emitting layer including a first host having a first hole transporting host and a first electron transporting host and a dopant emitting light of the second wavelength, and a second sub-light emitting layer including a second host and a second hole transporting host, but not including the dopant. The light emitting device provides improved light emitting efficiency.
