A light-emitting device comprising:
- a substrate;
- a first electrode on the substrate, the first electrode comprising holes and having inclined surfaces along peripheries of the holes;
- second electrodes on the substrate, each of which is in a respective one of the holes of the first electrode;
- light-emitting elements between the first electrode and the second electrodes, the light-emitting elements being electrically connected to the first electrode and the second electrodes;
- and
- an insulating pattern on the inclined surfaces and between respective ones of the inclined surfaces and the light-emitting elements,
- wherein the insulating pattern extends completely across and under the respective ones of the light-emitting elements,
- wherein the first electrode comprises a first metal bonding layer,
- wherein the holes of the first electrode extend through the first metal bonding layer, and
- wherein the insulating pattern extends through the holes to protrude into the first metal bonding layer.
