1. A display apparatus comprising:
a liquid crystal panel; and
a light source apparatus comprising a substrate and a plurality of light emitting diodes (LEDs) disposed on the substrate, wherein the substrate comprises a conductive layer and a protective layer disposed on the conductive layer,
wherein each LED of the plurality of LEDs comprises a lower surface in contact with a first feeding pad and a second feeding pad, wherein the first feeding pad and the second feeding are formed on the substrate and are in contact with the conductive layer,
wherein the lower surface of each LED of the plurality of LEDs comprises a first contact area configured to be in contact with the first feeding pad, a second contact area configured to be in contact with the second feeding pad, and a non-contact area distinct from the first contact area and the second contact,
wherein each of the first contact area and the second contact area is smaller than the non-contact area,
wherein the protective layer comprises a first window and a second window respectively exposing the first feeding pad and the second feeding pad to an outside, and at least one tunnel disposed between the first window and the second window, and
wherein at least one side of the at least one tunnel is formed by the conductive layer.
