ORGANIC ELECTROLUMINESCENCE ELEMENT |
摘要 |
<p>In an organic electroluminescent device constructed by providing at least an emitting layer using an organic material between a hole injection electrode and an electron injection electrode, in forming an emitting layer having a dopant doped into a host material, a dopant having a condensed ring obtained by condensing three or more rings is used, and the difference between the highest occupied molecular orbital in the host material and the highest occupied molecular orbital in the dopant is in a range from - 0.3 eV to + 0.3 eV.</p> |
