Abstract
A light emitting device includes a printed circuit board (PCB) substrate, a first ink layer covering the PCB substrate, the first ink layer having a first refractive index, light emitters on the first ink layer, and a second ink layer on the first ink layer and spaced apart from the light emitters, the second ink layer having a second refractive index different from the first refractive index.
