ABSTRACT:
The present invention provides an organic EL device including a pair of electrodes consisting of a positive electrode and a negative electrode; a plurality of banks which is disposed between the pair of electrodes and insulates the positive electrode and the negative electrode; and an organic EL light-emitting material in a plurality of gaps formed by bank partitions, wherein if the distance between the bank partitions in the gap at one electrode side is d, the distance between the bank partitions except at the one electrode side is d′ and the distance between the bank partitions at the other electrode side to the one electrode side is d″, then at least one of the gaps satisfies d>d″, and the distance between the bank partitions in the gap progressively satisfies d−d′≧0 from the one electrode side to the other electrode side. The present invention also provides an efficient method of manufacturing the organic EL device.
