Abstract
The present invention relates to an electroluminescent device and method of manufacturing the same, capable of reducing the loss of light propagated toward the lateral side of the device and increasing the amount of light propagated to the front of the display to improve the brightness and efficiency of the device, in such a way that a transparent conductive film or a luminescent layer is made of compound having an orientation and is then etched to make the transparent conductive film or the luminescent layer in a protrusion shape. For this, an electroluminescent device comprises a substrate, a first electrode formed on the substrate, a luminescent layer formed on the first electrode, and a second electrode formed on the luminescent layer, wherein at least one of the first electrode, the luminescent layer and the second electrode is formed to have a protrusion at its surface is formed to have a surface of a protrusion shape at its given region.
