Abstract:
1. An organic electroluminescence device comprising: a substrate on which a first electrode is provided on the surface and including at least one projection, a functional layer provided so as to cover the projection, and a second electrode formed on that functional layer, the organic electroluminescence device characterized in that a cross-sectional contour of an end of a surface of the projection contacting the functional layer is a shape shown by the following equation: wherein, h is a maximum height (nm) of the projection from its base, x is a distance (nm) in a horizontal direction having as its origin the position where y=h/2, y is a distance (nm) in a thickness direction of the projection, and r is a coefficient showing a smoothness of the cross-sectional shape) and the coefficient r satisfies the following relation: wherein, k=t/h and t is a thickness (nm) of the functional layer.
