Abstract
An active matrix electroluminescent display having an array of pixel electrodes disposed on a transparent substrate. Each pixel electrode having an associated electronic circuit formed intermediate the pixel electrode and the transparent substrate to which it is electrically connected. The array of pixel electrodes are overlayed with an electroluminescent stack and a transparent ITO conductive layer. The surface of each pixel electrode is uniformly texturized to enhance the brightness of the pixel element when it is activated to its luminous state by its associated electronic circuit.
