Abstract
An electroluminescent display having top and bottom stripe-shaped electrodes extending in first and second directions perpendicular to each other so that a single electroluminescent organic thin film is sandwiched by the top and bottom electrodes, crossing regions of the top and bottom electrodes being aligned in matrix, and sub-pixels being formed in the crossing regions. Pixels are formed by a plurality of the sub-pixels, and shielding walls are provided at boundaries of the pixels. Shielding walls may also be provided at a boundary between each of the sub-pixels, and at least one sub-pixel in each pixel has a light emission dopant added to a host light-emission layer or region.
