Abstract
A display device may include a light emitting element including a first end having a first surface, and a second end having a second surface parallel to the first surface, an organic pattern that overlaps the light emitting element and exposes the first and second surfaces, a first electrode disposed on a substrate and electrically contacting the first end, and a second electrode disposed on the substrate and spaced apart from the first electrode, and electrically contacting the second end. A surface area of the first surface may be less than that of the second surface. A top surface of the organic pattern may be a curved surface.
Claims20
A display device comprising:
- a light emitting element disposed on a substrate, and comprising:
- a first end including a first surface;
- and
- a second end including a second surface parallel to the first surface;
- an organic pattern that overlaps the light emitting element and exposes the first surface and the second surface;
- a first electrode disposed on the substrate and electrically contacting the first end;
- and
- a second electrode disposed on the substrate and spaced apart from the first electrode, and electrically contacting the second end, wherein
- a surface area of the first surface is less than a surface area of the second surface, and
- a top surface of the organic pattern is a curved surface.
A display device comprising:
- a light emitting element disposed on a substrate at regular intervals in a first direction, and comprising:
- a first end including a first surface;
- and
- a second end including a second surface parallel to the first surface;
- a plurality of organic patterns respectively disposed on the light emitting elements, and each exposing the first surface and the second surface;
- a first electrode electrically contacting the first end;
- and
- a second electrode electrically contacting the second end, wherein
- the first electrode and the second electrode are disposed on the substrate and spaced apart from each other in a second direction intersecting the first direction,
- a top surface of each of the plurality of organic patterns is a convex surface protruding in a third direction intersecting the first direction and the second direction.
A method of fabricating a display device, comprising:
- preparing a gravure substrate including a groove;
- disposing, into the groove, ink including a base resin and light emitting elements dispersed in the base resin;
- transferring the ink disposed in the groove to a blanket;
- transferring, to the substrate, the ink transferred to the blanket;
- forming an organic pattern by removing at least a portion of the base resin;
- and
- forming, on the substrate, a first electrode and a second electrode partially overlapping the light emitting element, and spaced apart from each other in a direction.
