Abstract
An organic EL display of the present invention includes a plurality of organic EL devices, each including a first electrode, an intermediate insulating film disposed on the first electrode so as to have an exposed portion in which the first electrode is partially exposed, an organic layer disposed on the exposed portion, and a second electrode disposed on the organic layer. The organic layer has, on a part disposed on the exposed portion, a thick film portion disposed around the center of the exposed portion and a thin film portion disposed around the end of the exposed portion and having a smaller thickness than the thick film portion, and the thin film portions of the adjacent organic EL devices are substantially equal in width.
Claims6
An organic EL display comprising:
- a plurality of organic EL devices, each including:
- a first electrode having an exposed portion thereof,
- a second electrode, and
- an organic portion between the first and the second electrodes, the organic portion is formed on at least the exposed portion of the first electrode,
- wherein the organic portion has a thick portion and a thin portion around the thick portion, and
- wherein ΔW represents a variation in a width of the thin portion between adjacent organic EL devices that are located in an area, and WA represents an average width of the exposed portions of the first electrodes in the adjacent organic EL devices in the area, and
- wherein ΔW/WA is 0.05 or less.
