Abstract:
A method of forming an electroluminescent (EL) display having top and bottom stripe-shaped electrodes which are aligned in matrix and extend perpendicular to each other to sandwich a single EL organic thin film between the top and bottom electrodes in crossing regions of the top and bottom electrodes to define sub-pixels, wherein a pixel includes a plurality of sub-pixels, the method comprising the steps of:providing shielding walls so that each pixel is interposed between an adjacent two of the shielding walls;depositing a host light emission material in a first direction onto a first area of each pixel; andconcurrently depositing a first dopant in a second direction different from the first direction onto a second area of each pixel different from the first area of each pixel,wherein the sub-pixels of each pixel emit light of different colors from one another.
