Patent ID: 7375463

Claim:
An organic EL display comprising: an organic EL element which comprises a front electrode, a back electrode facing the front electrode, and an organic layer interposed between the front and back electrodes and including an emitting layer; a thin-film transistor; a source electrode connected to a source of the thin-film transistor; a drain electrode connected between a drain of the thin-film transistor and one of the front and back electrodes; an insulating layer with light transmission property which comprises a back surface facing the front electrode and a front surface as a light output surface; and an outcoupling layer which is disposed on a back side of the insulating layer, faces the organic EL element, overlies the source and drain electrodes, and is provided with a through-hole through which the front or back electrode is connected to the drain electrode, wherein the outcoupling layer comprises a first portion as a layer with light transmission property and second portions which are dispersed in the first portion and differ in optical property from the first portion, and wherein an array of the second portions forms a triangular lattice.
