SEMICONDUCTOR LIGHT EMITTING DEVICE FOR A DISPLAY PANEL, A SUBSTRATE STRUCTURE FOR A DISPLAY PANEL, AND A DISPLAY DEVICE INCLUDING THE SAME

Discussed is a semiconductor light emitting device for a display panel, a substrate structure for a display panel, and a display device including the substrate structure. A display device including a semiconductor light emitting device can include a first electrode and a second electrode spaced apart from each other on a predetermined substrate, an insulating layer disposed on the first and second electrodes, a first barrier wall disposed on the insulating layer and including a first assembling hole and a semiconductor light emitting device disposed in the first assembling hole of the first barrier wall. Also, the semiconductor light emitting device can include a light emitting structure, a passivation layer on the light emitting structure, and a first reflective alignment structure disposed in the light emitting structure.
