Abstract: A light emitting device substrate includes an insulating layer, a plurality of upper pads spaced apart from each other in a matrix pattern on the insulating layer, a first circuit pattern inside the insulating layer, the first circuit pattern electrically connecting some of the plurality of upper pads to each other, a second circuit pattern inside the insulating layer, the second circuit pattern being under the first circuit pattern and electrically connected to the first circuit pattern, and a plurality of lower pads spaced apart from each other under the insulating layer, a number of the plurality of lower pads being smaller than a number of the plurality of upper pads, and at least one of the plurality of lower pads being electrically connected to two or more upper pads of the plurality of upper pads via the first circuit pattern and the second circuit pattern.

Abstract: A light-emitting device package includes a circuit board, a light-emitting device mounted on the circuit board, a reflective sheet disposed on the circuit board, the reflective sheet including an opening penetrating through the reflective sheet, wherein the light-emitting device is disposed within the opening, an inclined portion surrounding the opening when viewed in a plan view, and being inclined at a first angle with respect to an upper surface of the circuit board, and a flat extension portion surrounding the inclined portion when viewed in a plan view, and being parallel to the upper surface of the circuit board, and a diffuser plate disposed at a first vertical distance from the upper surface of the circuit board. An air gap is disposed between the upper surface of the circuit board and the flat extension portion.
