摘要： A light emitting device is closed. More particularly, a light emitting device capable improving light-extraction efficiency is disclosed. The light emitting device includes a plurality of layers including a reflector layer. The reflector layer has the maximum reflectivity at an incidence angle more than zero degrees and less than an angle θ. The angle θ is represented by the equation θ=Sin−1[n2/n1] (where, n1 is the maximum refractive index of the plurality of layers constituting the light emitting device, and n2 is the refractive index of an external background material).
