A method and a device for manufacturing an electroluminescent display, by means of which a first pattern of electrodes (2) is provided on a flat surface (1) on which a layer of organic electroluminescent material (7) is subsequently deposited. A mask (10) with strips of mask material (11) is formed on a separate support (14), the strips being separated from each other by spaces (12) which correspond to a second pattern of electrodes (8). Subsequently, said mask is transferred to the layer of electroluminescent material in a dry manner by pressing the support onto the substrate. After transferring the mask (10), a second electrode material (13) is deposited, the electrodes of the second pattern being formed in the spaces in the mask. The layer of electroluminescent material (7) may be deposited by vapor deposition, spin-coating or screen-printing.
