A self-light-emitting type organic electroluminescence device which makes it possible to restrain to the utmost the absorption of light in an electrode layer, to efficiently take out the light and thereby to obtain sufficient luminance efficiency and the like, in the case of emitting the light through the electrode layer. In an organic electroluminescence device comprising a light-emitting layer (3) comprised of an organic material based the light-emitting layer (3) being sandwiched between a first electrode (2) and a second electrode (4), and light emitted from the light-emitting layer (3) being taken out to at least one of the side of the first electrode (2) and the side of the second electrode (4), the light absorbance of the electrode or electrodes on the side of taking out the light, of the first electrode (2) and the second electrode (4), is not more than 10%.
An organic electroluminescence device comprising a light-emitting layer comprised of an organic material, said light-emitting layer being positioned between a first electrode and a second electrode, and light from said light-emitting layer being transmitted through at least one of said first electrode and said second electrode, wherein
