摘要:
An organic electroluminescence element is disclosed which comprises a cathode, a light emission layer containing a host compound and a dopant compound, and at least one first layer provided between the cathode and the light emission layer, wherein the dopant compound is a phosphorescent compound, and the first layer is comprised of a first material having a molecular weight of from 500 to 2000, a maximum fluorescence wavelength of not longer than 415 nm, and an F to (H+F) ratio F/(H+F) of from 0 to 0.9 in which F and H represent the fluorine atom number and the hydrogen atom number in the molecule of the material, respectively.
