LIGHT-EMITTING DEVICES HAVING MULTIPLE ENCAPSULATION LAYERS WITH AT LEAST ONE OF THE ENCAPSULATION LAYERS INCLUDING NANOPARTICLES AND METHODS OF FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an encapsulation layer that protects an active element from another element and increases the optical output of a LED small cube whose optical quality does not decrease even with use of high-flux LED groups having comparatively short wave length (for example, 525 nm).

SOLUTION: A light-emitting device 10 includes an active region 13 that is configured to emit light responsive to a voltage applied thereto. A first encapsulation layer 16 at least partially encapsulates the active region 13 and includes a matrix material and nanoparticles, which modify at least one physical property of the first encapsulation layer 16.
