LIGHT-EMITTING ELEMENT, DETECTION DEVICE, AND PROCESSING DEVICE

摘要

A light-emitting element according to an embodiment of the present invention includes a light-transmissive substrate, a first electrode, a light-transmissive first layer, a light-transmissive second electrode, a light-emitting layer, and a second layer. The refractive index of the first layer is lower than the refractive index of the substrate. At least a portion of the first layer is disposed between the first electrode and a portion of the substrate. The second electrode is disposed between the first electrode and at least a portion of the first layer. The light-emitting layer is disposed between the first electrode and the second electrode. At least a portion of the second layer is disposed between the first electrode and at least a portion of the first layer. The second layer is configured such that the advancing direction of light entering the second layer can be changed.
