ELECTROLUMINESCENT ELEMENT, LIGHTING EQUIPMENT, AND DISPLAY DEVICE

摘要

There is a huge demand for increase in the luminance of electroluminescent elements and decrease in the electric power consumption. An objective of the present invention is to provide such an electroluminescent element as to satisfy the demand, as well as lightening equipment and display devices with high performance by utilizing the element. Provided is an electroluminescent element comprising a transparent substrate, and a first electrode layer, a light-emitting layer, and a second electrode layer, which layers are layered on the substrate in this order, wherein a surface of the transparent substrate on the side of the first electrode layer has a light-directional structure. A lightening device and a display device including this electroluminescent element are also provided.
