Abstract

Provided are a display apparatus and a method of manufacturing the same. The display apparatus includes a support substrate, a driving layer provided on the support substrate and including a driving element configured to apply power to a pixel electrode, and a light-emitting layer provided on the driving layer.

Claims (17)

1. A display apparatus comprising:

a support substrate;

a driving layer provided on the support substrate and comprising a driving element;

a light-emitting layer comprising a first semiconductor layer, an active layer, and a second semiconductor layer stacked on the driving layer, the light-emitting layer having an ion implantation region configured to divide light emitted from the active layer into a plurality of subpixels;

a first electrode electrically connected to the first semiconductor layer; and

a second electrode electrically connected to the second semiconductor layer.

2. The display apparatus of claim 1 , further comprising a bonding layer provided between the support substrate and the driving layer.

3. The display apparatus of claim 1 , wherein the second electrode comprises a common electrode.

4. The display apparatus of claim 1 , wherein the second electrode comprises a transparent electrode and disposed to cover the second semiconductor layer.

5. The display apparatus of claim 1 , wherein the second electrode comprises:

an opaque electrode; and

a window region configured to transmit light emitted from the active layer.

6. The display apparatus of claim 1 , wherein the second electrode comprises a trench structure provided between adjacent subpixels, among the plurality of subpixels.

7. The display apparatus of claim 6 , wherein the trench structure of the second electrode is configured to reflect light emitted laterally from the active layer.

8. The display apparatus of claim 6 , wherein, in a cross-sectional view, a bottom of the trench structure of the second electrode is above a surface of the active layer facing the second semiconductor layer.

9. The display apparatus of claim 1 , further comprising a plurality of color conversion layers configured to convert light emitted from the light-emitting layer into different color lights.

10. The display apparatus of claim 2 , wherein the bonding layer is provided directly between the support substrate and the driving layer.
