Display apparatus and manufacturing method thereof
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.
1. A display apparatus comprising:
a substrate;
a bank layer on the substrate, wherein the bank layer defines a concave portion, and the bank layer comprises:
a first bank; and
a second bank on the first bank,
wherein a width of the second bank is less than a width of the first bank when viewed from a plan view in a thickness direction of the substrate such that the first bank and the second bank collectively define a step portion;
a light-emitting diode on the substrate in the concave portion defined by the bank layer;
a pixel separating layer on the second bank surrounding the light-emitting diode; and
a light dispersion layer arranged on the light-emitting diode and the pixel separating layer, wherein the light dispersion layer comprises a transparent medium and micro-particles in the transparent medium such that the light dispersion layer scatters light emitted from the light-emitting diode.
2. The display apparatus of claim 1 , further comprising:
an inorganic insulating layer between the light-emitting diode and the light dispersion layer, and between the bank layer and the pixel separating layer, wherein the inorganic insulating layer covers the light-emitting diode.
3. The display apparatus of claim 2 , further comprising:
a lens arranged between the inorganic insulating layer and the light dispersion layer, wherein the lens covers the light-emitting diode between the light-emitting diode and the pixel separating layer.
4. The display apparatus of claim 3 , wherein a refractive index of the lens is lower than a refractive index of the light-emitting diode, and is higher than a refractive index of air.
5. The display apparatus of claim 3 , wherein the pixel separating layer has a height lower than a height of the lens, and has a concave upper surface.
6. The display apparatus of claim 3 , wherein the pixel separating layer has a height lower than a height of the lens, and has a convex upper surface.
7. The display apparatus of claim 1 , further comprising:
a lens between the light-emitting diode and the pixel separating layer, and arranged below the light dispersion layer, wherein the lens covers the light-emitting diode.
8. The display apparatus of claim 7 , wherein a refractive index of the lens is lower than a refractive index of the light-emitting diode, and is higher than a refractive index of air.
9. The display apparatus of claim 7 , wherein the pixel separating layer has a height lower than a height of the lens and has a convex upper surface.
10. The display apparatus of claim 3 , wherein the pixel separating layer has a height lower than a height of the lens and has a concave upper surface.
11. The display apparatus of claim 1 , wherein the pixel separating layer comprises a light reflective material.
12. The display apparatus of claim 1 , wherein the pixel separating layer comprises a light-scattering material.
13. The display apparatus of claim 1 , wherein the pixel separating layer comprises a material capable of absorbing at least a portion of light.
14. The display apparatus of claim 1 , further comprising:
a first electrode in the concave portion and connected to one electrode of the light-emitting diode; and
a second electrode connected to the other electrode of the light-emitting diode.
15. The display apparatus of claim 14 , wherein the second electrode extends and is connected to a conductive layer on the bank layer.
