A functional device having, on a substrate, a pair of electrodes, a functional layer which is sandwiched between the electrodes and has an output that varies in accordance with an applied electric current, and a terminal arranged to apply an electric current to at least one of the electrodes, wherein an insulator is arranged between the electrodes and the density of the insulator decreases as the distance from the terminal increases, or wherein at least one of the electrodes has a notch section, and the ratio of the area of the notch section to the area of the electrode decreases as the distance from the terminal increases. This is an improved functional device which is excellent in production suitability and gives a uniform in-plane output, and can be rendered, in particular, an organic electroluminescence device. |
