Electroluminescence element
Abstract:
Disclosed herein is an electroluminescence element that is excellent in color rendering properties and has a long service life as a white light-emitting element, that is, high durability. The electroluminescence element (100) includes: a substrate (1); a first electrode (2); a functional layer (20) including at least one light-emitting layer (5); and a second electrode (8), wherein the at least one light-emitting layer (5) contains a quantum dot material (11), and wherein when a particle size at a cumulative frequency of 10% and a particle size at a cumulative frequency of 90% in a volume-based cumulative particle size distribution of the quantum dot material (11) are defined as d10 (nm) and d90 (nm), respectively, the quantum dot material (11) satisfies d90−d10≧3 nm.
