Electroluminescence device and display unit

摘要

Providing a particle distributed electroluminescent device which is improved in luminescent color control, prevention of luminescent color change over time and heavy circuit load, and/or representation of a delicate gradation sequence, as well as capable of providing high brightness and luminous efficiency, and a display unit using such an electroluminescence device. Two types of luminescent particles, each having a dielectric core and a fluorescent coating layer are used as luminescent particles distributed in a luminescent layer of a particle distributed electroluminescence device. The dielectric cores of the two types of luminescent particles are formed of dielectric materials having different dielectric constants with each other.
