1. A light emitting device comprising:
a first electrode disposed on a substrate;
a second electrode spaced apart from the first electrode, the first electrode and the second electrode being disposed on a same layer;
an insulating pattern disposed between the first electrode and the second electrode and overlapping a portion of the first electrode and a portion of the second electrode in a plan view;
at least one light emitting element disposed on the insulating pattern, and including a first end and a second end in a longitudinal direction of the at least one light emitting element;
a first bank disposed on the first electrode, and a second bank disposed on the second electrode;
a first reflective electrode disposed on the first bank and electrically connected with the first electrode; and
a second reflective electrode disposed on the second bank and electrically connected with the second electrode, wherein
in a plan view, the insulating pattern has a width greater than a length of the at least one light emitting element.
