6. A display apparatus comprising:
semiconductor light-emitting devices;
a substrate comprising a wiring electrode electrically connected to the semiconductor light-emitting devices,
wherein the substrate comprises:
a base portion;
assembly electrodes disposed on the base portion to extend in one direction;
a dielectric layer positioned to cover the assembly electrodes; and
a partition wall portion located on the dielectric layer and shaped to define cells, wherein the semiconductor light-emitting devices are placed on a respective cell, of the cells, along an extension direction of the assembly electrodes;
an organic layer that fills the cells; and
a planarization layer positioned on the organic layer and shaped to define a first plurality of holes and a second plurality of holes that respectively overlap a cell, of the cells,
wherein each of the first plurality of holes is shaped to expose a respective one of the semiconductor light-emitting devices; and
wherein each of the second plurality of holes is shaped to expose the organic layer.
