1. A light emitting device having a multi-layer structure, comprising:

  • a reflector layer having the maximum reflectivity at an incidence angle more than zero degrees and less than an angle θ

    ,wherein the angle θ

    is represented by the equation θ

    =Sin

    1
    [n2/n1] (where, n1 is the maximum refractive index of the multi-layers constituting the light emitting device, and n2 is the refractive index of an external background material).
