Abstract: Disclosed are a lens for a light-emitting device usable in a display apparatus or a lighting apparatus, and a method of manufacturing a light-emitting device package. The lens may include a lens body including a light-receiving portion provided in a lower surface of the lens body, a light-emitting portion provided on an upper surface of the lens body, and a recess provided at a center of the upper surface of the lens body, and a flat portion provided in a horizontal shape on a bottom surface of the recess perpendicularly to a main emission line of light emitted from a light-emitting device to emit at least a part of light received through the light-receiving portion, upward. A diameter of the flat portion may be 1/100 to 1/10 of an inlet diameter of the light-receiving portion.
