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 (25)

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;

a pixel disposed in the first pixel forming plate and including a first subpixel, a second subpixel, and a third subpixel that display different colors from each other;

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

light emitting elements disposed on the first buffer layer and corresponding to the first, second, and third subpixels; and

a first encapsulation layer covering the light emitting elements.

2 . The display of claim 1 , wherein

one of the first, second, and third subpixels is narrower and longer than the other of the first, second, and third subpixels.

3 . The display of claim 1 , wherein

the pixel further includes a fourth subpixel displaying a same color as the second subpixel, and

the second and fourth subpixels are aligned in a first direction and the first and third subpixels are aligned in a second direction crossing the first direction.

4 . The display of claim 1 , wherein

one or more of the first, second, and third subpixels has a rhombus shape.

5 . The display of claim 1 , wherein

one or more of the first, second, and third subpixels has a quadrilateral shape.

6 . The display of claim 1 , wherein

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

7 . The display of claim 1 , wherein

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

8 . The display of claim 1 , further comprising:

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

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

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