Patent ID: 8053983

Claim:
An organic EL display comprising: an organic EL element comprising an organic layer including a light emitting layer, and a pair of electrode layers on both upper and lower sides of the organic layer, the organic layer comprising a first organic material; a capping layer on the organic EL element, comprising a second organic material having a glass transition point lower than that of the first organic material; a protective layer on the capping layer; and a partition wall around the organic EL element, wherein the capping layer covers at least a lower part of the partition wall while an upper part of the partition wall is exposed from the capping layer, the capping layer has an optical thickness to resonate a traveling wave of light traveling from the capping layer toward the protective layer and a reflective wave of light traveling from an upper layer of the electrode layers toward the protective layer, and the capping layer lies in a region enclosed in the partition wall and is interposed between the protective layer and the organic EL element.
