Abstract
An organic EL device includes a substrate, a first electrode layer formed on the substrate, an organic EL layer formed on the first electrode layer, and a second electrode layer formed on the organic EL layer. A distribution characteristic of light emitted from the first electrode layer into the substrate has a luminance in a direction of a first angle of 20 to 50 degrees measured with respect to an axis perpendicular to the substrate that is relatively high as compared to luminance in other angular directions.
