摘要： An organic electroluminescence device including at least an anode, an emitting layer, an electron-transporting region and a cathode in sequential order, wherein the emitting layer contains a host and a dopant which gives fluorescent emission of which the main peak wavelength is 550 nm or less; the affinity Ad of the dopant is equal to or larger than the affinity Ah of the host; the triplet energy ETd of the dopant is larger than the triplet energy ETb of the host; and a blocking layer is provided within the electron-transporting region such that it is adjacent to the emitting layer, and the triplet energy ETb of the blocking layer is larger than ETh.

摘要： An organic electroluminescence device includes: an anode; a cathode; and a luminescent layer (5) provided between the anode and the cathode. In the organic electroluminescence device, the luminescent layer (5) includes two or more doped regions (51) each of which contains a luminescent dopant, and at least one non-doped region (52) in which no luminescent dopant is contained.
