Abstract: A display device includes a substrate having a first surface in which a light-emitting element is disposed, a second surface, and a first lateral side; a connecting electrode disposed on the first surface; a first insulating layer disposed on the connecting electrode and including a contact hole; a first upper pad electrode electrically connected to the connecting electrode, the first upper pad electrode having a first thickness in an area not overlapping the contact hole and having a second thickness in an area overlapping the contact hole; a second upper pad electrode disposed on the first upper pad electrode and having a substantially flat profile; a lower pad disposed on the second surface of the substrate; and a side wiring electrically connecting the second upper pad electrode and the lower pad, the side wiring surrounding the first surface, the first lateral side, and the second surface of the substrate.

Abstract: A display device includes, a substrate including a first surface and a second surface opposite to the first surface; a light emitting element on the first surface of the substrate; a top surface pad on the first surface of the substrate and spaced from the light emitting element; a driving circuit on the second surface of the substrate to apply a driving signal for driving the light emitting element; a top surface connection line between the first surface of the substrate and the top surface pad to electrically connect the top surface pad to the light emitting element; an interlayer insulating layer between the top surface connection line and the top surface pad; and a side wiring on the top surface pad to connect the top surface pad to the driving circuit.
