1. A unit pixel, comprising:
a substrate;
a plurality of light emitting devices disposed on the substrate;
an adhesive layer disposed between the plurality of light emitting devices and the substrate and bonding the plurality of light emitting devices to the substrate; and
a moisture barrier structure configured to block an exposure of an outer region of the adhesive layer such that the adhesive layer is prevented from moisture damage, the moisture barrier structure further comprising:
a first structure comprising an insulating layer covering the adhesive layer;
a second structure disposed on the first structure and having a step adjustment layer;
covering the adhesive layer and the plurality of light emitting devices;
wherein the unit pixel further comprises:
plurality of connection layers disposed on the step adjustment layer and corresponding to the plurality of light emitting devices;
an insulation material layer covering the plurality of connection layers,
wherein the adhesive layer has a smaller area than an area of the substrate, and
wherein the insulation material layer covers side surfaces of the step adjustment layer along with side surfaces of the plurality of connection layers.
