Abstract
An electroluminescent device includes a tin oxide electrode having a textured surface with a phosphor layer interposed between dielectric layers overlying the textured surface. The textured surface propagates through the overlying layers so as to reduce the amount of generated light trapped in the device structure and increase the output brightness of the device.
