ORGANIC ELECTROLUMINESCENT ELEMENT, LIGHTING DEVICE AND DISPLAY DEVICE |
摘要 |
<p>An organic electroluminescent element which contains at least one light emitting layer that is sandwiched between a positive electrode and a negative electrode. This organic electroluminescent element is characterized in that: at least one of the light emitting layer(s) contains at least one light emitting dopant and at least one host; at least one of the light emitting dopant(s) is a phosphorescent dopant that has an emission peak wavelength of 470 nm or less and a HOMO value of from -4.50 eV to -5.50 eV; and at least one of the host(s) is a compound represented by general formula (1) or a specific compound, which has a HOMO value of from -4.60 eV to -5.10 eV.</p> |
