Abstract
The present disclosure relates to the structure of a micro light-emitting device and an alignment substrate. The light-emitting device according to one embodiment includes an inclined side surface having a three-dimensional shape. The inclined side surface is formed to protrude from one surface of the micro light-emitting device, has magnetism, and includes two different electrodes formed in one direction. In this case, among the two electrodes, one electrode may be formed on a mesa portion, and the other electrode may be formed on the inclined side surface.
Claims5
A three-dimensional shaped micro light-emitting device comprising:
- a structure including an inclined side surface, p-contact, p-GaN, n-contact, n-GaN, a substrate, and a wind resistance structure,
- wherein the inclined side surface has a circular cone shape or a pyramid shape,
- wherein the structure including the inclined side surface has magnetism and protrudes from the p-GaN,
- wherein the p-contact and the n-contact form a first electrode and a second electrode, respectively,
- wherein the p-contact is disposed to contact the structure including the inclined side surface,
- wherein the n-contact is disposed on a mesa portion,
- wherein the inclined side surface, the p-contact, the p-GaN, the n-contact, and the n-GaN are disposed on a first surface of the substrate, and the wind resistance structure is disposed on a second surface of the substrate opposite to the first surface of the substrate.
