Organic electroluminescent element and electronic device
An organic electroluminescence device includes two or more emitting units disposed between an anode and a cathode, and an intermediate layer, in which the intermediate layer contains a phenanthroline compound, the laminated emitting unit includes a first emitting layer containing a first host material and a second emitting layer containing a second host material, and a triplet energy T.sub.1(H1) of the first host material and a triplet energy T.sub.1(H2) of the second host material satisfy a relationship of a numerical formula (Numerical Formula 3),
T.sub.1(H1)>T.sub.1(H2) (Numerical Formula 3).
ORGANIC COMPOUND, LIGHT-EMITTING COMPONENT, AND DISPLAY PANEL
An organic compound, a light-emitting component, and a display panel are disclosed. The organic compound has a structure shown as general formula (1):
##STR00001##
This organic compound can enhance conjugated effect and resonance effect of materials applied into the light-emitting component by having a heterocyclic group and an amino group at a same time. Therefore, material performances can be improved, a luminous efficiency of the light-emitting component can be improved, and a light-emitting service life of the light-emitting component can be extended.
