An organic electroluminescence device having RGB pixel areas, wherein optical compensation layers are respectively arranged between the red light emitting layer and the first organic functional layer as well as between the green light emitting layer and the first organic functional layer, the optical compensation layers are made of a first hole transport material and a second hole transport material, the first hole transport material has a triplet-state energy level ≥2.48 eV and a HOMO energy level ≤−5.5 eV, the second hole transport material has a HOMO energy level >−5.5 eV, and the difference between the HOMO energy level of the first hole transport material and the HOMO energy level of the second hole transport material is ≤0.2 eV. Its preparation process is simple, and it can significantly reduce power consumption of the light-emitting device so as to increase light-emitting efficiency.
