Organic electroluminescence element and display

A display having an organic electroluminescence element comprising 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.

A multicolor display comprising two or more kinds of organic electroluminescence elements, which emit lights with different maximum emission wavelengths according to electroluminescence, wherein at least one organic electroluminescence element of the elements is an organic electroluminescence element comprising 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.
