Abstract
A method of manufacturing a device includes: —a) a first step for the formation of a temporary structure that comprises electroluminescent structures separated by trenches and comprising an electroluminescent face, the electroluminescent structures being bonded by means of a bond layer on a temporary substrate; b) an assembly step bringing the electroluminescent structures into contact with a host face of a host substrate; and c) a step for removal of the temporary substrate; wherein the bond layer, that comprises an electrically conducting organic polymer material at least partially transparent to light radiation, is at least partly kept after step c) and forms an electrode common to the light emitting faces, with a thickness of more than 20 nm.
