Abstract
An organic EL device is disclosed that prevents degradation due to moisture and oxygen and that avoids the generation of dark spots even when a substrate covered with polymer or made of a resin is used. The organic EL device includes a substrate, a transparent electrode consisting of a plurality of electrode elements formed on the substrate, an organic EL layer formed on the transparent electrode, and a reflection electrode formed on the organic EL layer. The transparent electrode includes first and second transparent electrode elements. Each of the first transparent electrode elements is arranged alternately with each of the second transparent electrode elements. A side edge portion of each of the first transparent electrode elements overlaps a side edge portion of next second transparent electrode element through an insulation layer. The first transparent electrode elements are electrically insulated from the second transparent electrode elements.
