  • Patent number: 8115381
    Abstract: This invention provides a top-emission active matrix electroluminescent device including a substrate and a plurality of pixel areas formed within a display area of the substrate. Each of the pixel areas includes at least one sub-pixel area comprising at least, from top to bottom: a first conductive electrode layer, an electroluminescent layer, a second conductive electrode layer, a first reflective layer region, and a second reflective layer region. The first reflective layer region and second reflective layer region overlap each other in part. Some of the light rays emitted from the electroluminescent layer are reflected by the first reflective layer region and second reflective layer region, respectively, and are then directed upwards. The reflected light rays compensate the top-emitting light rays also emitted from the electroluminescent layer, reducing color shifts at different viewing angles due to the micro-cavity effect.
