Classification: CPC H | IPC H

Claim 15:
16. A display device comprising:
at least one first bank and a second bank disposed on a substrate and spaced apart from each other, wherein at least a part of each of the at least one first bank and the second bank protrudes toward an upper surface of the substrate;
a first electrode that covers the at least one first bank and a second electrode that covers the second bank;
a first insulating layer that covers the first electrode, the second electrode, and a space between the first electrode and the second electrode;
a second insulating layer disposed on at least a part of the first insulating layer; and
a light-emitting element disposed on the second insulating layer between the first electrode and the second electrode, wherein
at least a part of a lower surface of the light-emitting element is chemically bonded to the second insulating layer,
the light-emitting element comprises:
a rod-like semiconductor core;
an insulation film surrounding the semiconductor core; and
a binding group coupled to the insulation film, and

the second insulating layer comprises a functional group, and
the chemical bond between the light-emitting element and the second insulating layer is formed by a chemical reaction between the binding group and the functional group.
