Abstract

A diode display includes a substrate having a first island and a second island spaced apart from each other, a first pixel disposed on the first island, and a second pixel disposed on the second island. The first pixel includes a first base layer, a first transistor on the first base layer, a first light emitting element electrically connected to the first transistor, and a first encapsulation layer covering the first light emitting element. The second pixel includes a second base layer, a second transistor on the second base layer, a second light emitting element connected to the second transistor, and a second encapsulation layer covering the second light emitting element.

Claims (26)

1. A display, comprising:

a first pixel forming plate;

a second pixel forming plate separated from the first pixel forming plate;

a bridge connecting the first pixel forming plate and the second pixel forming plate; and

a pixel disposed in the first pixel forming plate and including a red subpixel, a green subpixel, and a blue subpixel.

2. The display of claim 1 , wherein

one of the red subpixel, the green subpixel, and the blue subpixel is narrower and longer than the remaining red subpixel, green subpixel, and blue subpixel.

3. The display of claim 1 , wherein

the pixel further includes a green subpixel, and

the green subpixel is aligned in a first direction and the red subpixel and the blue subpixel are aligned in a second direction crossing the first direction.

4. The display of claim 1 , wherein

one or more of the red subpixel, the green subpixel, and the blue subpixel has a rhombus.

5. The display of claim 1 , wherein

one or more of the red subpixel, the green subpixel, and the blue subpixel has a quadrilateral.

6. The display of claim 1 , further comprising:

a first buffer layer disposed on the first pixel forming plate;

light emitting elements disposed on the first buffer layer and corresponding to the red subpixel, the green subpixel, and the blue subpixel; and

a first encapsulating layer covering the light emitting elements.

7. The display of claim 6 , wherein

the first encapsulation layer is in contact with an upper surface of the first pixel forming plate.

8. The display of claim 6 , wherein

the first encapsulation layer is in contact with an upper surface of the first buffer layer.

9. The display of claim 6 , further comprising:

a second buffer layer disposed on the second pixel forming plate and separated from the first buffer layer; and

a second encapsulating layer disposed on the second pixel forming plate and separated from the first encapsulation layer.

10. The display of claim 1 , wherein the bridge has a curved shape.
