1. A light emitting device, comprising:
a substrate;
a first electrode and a second electrode on the substrate and spaced from each other;
a first insulating layer on the substrate and the first and second electrodes, and including openings to partially expose opposing portions of the first and second electrodes adjacent an area between the first and second electrodes;
at least one light emitting element located in the opening; and
a second insulating layer disposed on the at least one light emitting element and fills the openings of the first insulating layer, the second insulating layer exposing both ends of the at least one light emitting element,
wherein a first end of the at least one light emitting element is connected to a first portion of the first electrode exposed by the opening, and
wherein a second end of the at least one light emitting element is connected to a second portion of the second electrode exposed by the opening.
