1. 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.
