An organic EL device includes a substrate body, a plurality of organic functional layers arranged on the substrate body in a given pattern and a partition for partitioning the plural organic functional layers. The partition includes at least a first partition part with a substantially trapezoidal cross-section provided on the substrate body and a second partition part with a substantially trapezoidal cross-section provided on the first partition part. The partition is formed so that a lower base of the cross-section of the second partition part can be shorter than an upper base of the cross-section of the first partition part.
