1. A display apparatus, comprising:
a substrate in which a plurality of pads are disposed;
a plurality of LEDs, wherein each LED from among the plurality of LEDs is electrically connected to a respective group of pads from among the plurality of pads and mounted on the substrate; and
a plurality of protrusion members, wherein each protrusion member from among the plurality of protrusion members protrudes from the substrate and is formed adjacent to a respective pad from among the plurality of pads without directly contacting any portion of any LED of the plurality of LEDs, and wherein each protrusion member from among the plurality of protrusion members supports an electrode pad of each of the plurality of LEDs to be fixed on the respective pads of the substrate, and
wherein a distance from a bottom surface of the plurality of LEDs to the substrate is larger than a distance from a top surface of the plurality of protrusion members to the substrate,
wherein each pad from among the plurality of pads corresponds to at least one respective protrusion member from among the plurality of protrusion members that is disposed to surround an outer surface of the pad,
wherein the respective group of pads comprises a first pad and a second pad adjacent to the first pad, and
wherein a protrusion member from among the plurality of protrusion members is disposed on outer surfaces of the first pad and the second pad except for a first surface of the first pad and a second surface of the second pad where the first pad and the second pad face each other.
