Abstract

A display apparatus includes a substrate; a light-emitting diode on the substrate; a pixel separating layer surrounding the light-emitting diode; and a light dispersion layer on the light-emitting diode and the pixel separating layer.

Claims (22)

1. A display device comprising:

a substrate;

a bank layer on the substrate, wherein the bank layer defines openings;

a light-emitting diode in each of the openings defined by the bank layer;

a pixel separating layer between the openings, wherein the pixel separating layer on the bank layer does not overlap the openings when viewed from a plan view in a thickness direction of the substrate; and

a light dispersion layer disposed on the light-emitting diode, wherein the light dispersion layer covers an entire portion of the pixel separating layer and an entire portion of the openings when viewed from the plan view in the thickness direction of the substrate,

wherein the light dispersion layer comprises micro-particles such that the light dispersion layer scatters light emitted from the light-emitting diode.

2. The display device of claim 1 , wherein the pixel separating layer has a convex upper surface.

3. The display device of claim 1 , further comprising:

a lens overlapping the light-emitting diode and having a convex upper surface.

4. The display device of claim 3 , wherein the pixel separating layer is between lenses and has a convex upper surface.

5. The display device of claim 3 , wherein the pixel separating layer is between lenses and has a concave upper surface.

6. The display device of claim 1 , further comprising:

an inorganic insulating layer between the light-emitting diode and the light dispersion layer.

7. The display device of claim 6 , further comprising:

a lens between the insulating inorganic layer and the light dispersion layer, wherein the lens overlaps the light-emitting diode.

8. The display device of claim 1 , wherein the pixel separating layer comprises a light reflective material.

9. The display device of claim 1 , wherein the pixel separating layer comprises a light-scattering material.

10. The display device of claim 1 , wherein the pixel separating layer comprises a material capable of absorbing at least a portion of light.

11. The display device of claim 1 , further comprising: a first electrode in each of the openings and connected to one electrode of the light-emitting diode; and a second electrode connected to the other electrode of the light-emitting diode.

12. The display device of claim 11 , further comprising a conductive layer on the bank layer and connected to the second electrode.

13. The display device of claim 12 , wherein the conductive layer is between the bank layer and the pixel separating layer.
