Abstract

A display apparatus includes a substrate, a light-emitting diode (“LED”) provided above the substrate, an insulating layer provided above the LED, and a wire grid polarizer (“WGP”) provided above the insulating layer.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate;
a light-emitting diode disposed above the substrate;
an insulating layer disposed above the light-emitting diode; and
a wire grid polarizer disposed above the insulating layer.

2. The display apparatus of claim 1 , wherein the insulating layer exposes an upper surface of the light-emitting diode.

3. The display apparatus of claim 2 , wherein the wire grid polarizer contacts the upper surface of the light-emitting diode.

4. The display apparatus of claim 2 , wherein a height of an upper surface of the insulating layer is equal to or less than a height of the upper surface of the light-emitting diode with reference to the substrate.

5. The display apparatus of claim 2 , wherein an opening which exposes the upper surface of the light-emitting diode is defined in the insulating layer.

6. The display apparatus of claim 2 , wherein the light-emitting diode comprises a p-n diode, a first contact electrode, and a second contact electrode,
wherein the first contact electrode and the second contact electrode are disposed in the upper surface of the light-emitting diode.

7. The display apparatus of claim 1 , further comprising:
a first electrode disposed above the substrate; and
a reflection layer interposed between the light-emitting diode and the first electrode.

8. The display apparatus of claim 7 , further comprising:
a pixel defining layer comprising a concave region which exposes a central portion of the first electrode,
wherein the reflection layer is disposed above the concave region.

9. The display apparatus of claim 7 , further comprising: a pixel protection layer disposed above the light-emitting diode.

10. The display apparatus of claim 9 , wherein the pixel protection layer covers the reflection layer.

11. The display apparatus of claim 9 , wherein the pixel protection layer further comprises fine particles.

12. The display apparatus of claim 9 , further comprising:
a second electrode disposed above the pixel protection layer,
wherein an opening which exposes at least a part of the upper surface of the light-emitting diode is defined in the pixel protection layer, and
wherein the second electrode contacts at least a part of the upper surface of the light-emitting diode through the opening.

13. The display apparatus of claim 1 , further comprising:
a first electrode and a second electrode disposed above a same layer of the substrate,
wherein the light-emitting diode is electrically connected to the first electrode and the second electrode.

14. The display apparatus of claim 13 , wherein the light-emitting diode comprises an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface and further comprises a metal layer disposed to cover the side surface of the light-emitting diode.

15. The display apparatus of claim 13 , wherein the light-emitting diode comprises a p-n diode, a first contact electrode, and a second contact electrode,
wherein the first contact electrode and the second contact electrode are disposed in a same side.

16. The display apparatus of claim 1 , further comprising:
a thin film transistor disposed above the substrate and comprising a semiconductor layer, a gate electrode, a source electrode, and a drain electrode.

17. A display apparatus comprising:
a substrate;
a thin film transistor disposed above the substrate;
a first electrode electrically connected to the thin film transistor;
a light-emitting diode disposed above the first electrode and comprising a first contact electrode electrically connected to the first electrode and a second contact electrode spaced apart from the first contact electrode at a predetermined gap;
an insulating layer which covers at least a part of the light-emitting diode; and
a wire grid polarizer disposed above the insulating layer.

18. The display apparatus of claim 17 , wherein the insulating layer comprises an open portion which exposes at least a part of the second contact electrode.

19. The display apparatus of claim 18 , wherein the second contact electrode and the wire grid polarizer are in contact with each other through the open portion.

20. The display apparatus of claim 17 , further comprising:
a pixel protection layer which covers the first electrode and the light-emitting diode and in which an open portion which exposes at least a part of the second contact electrode is defined; and
a second electrode spaced apart from the first electrode and electrically connected to the second contact electrode through the open portion.
