1. A display device comprising:
a first electrode disposed on a substrate;
a second electrode spaced apart from the first electrode;
a first insulating layer disposed on the first electrode and the second electrode;
light emitting elements disposed on the first electrode and the second electrode on the first insulating layer;
a bank layer disposed on the first insulating layer and including an opening in which the light emitting elements are disposed;
a contact electrode layer disposed on the light emitting elements and the bank layer, the contact electrode layer including a first contact electrode and a second contact electrode that are spaced apart from each other on the light emitting elements;
an intermediate layer disposed on the contact electrode layer and including a first pattern portion disposed on the first contact electrode and a second pattern portion spaced apart from the first pattern portion and disposed on the second contact electrode; and
a connection electrode layer disposed on the intermediate layer and including a first connection electrode disposed on the first pattern portion and a second connection electrode spaced apart from the first connection electrode and disposed on the second pattern portion,
wherein side edges of the first contact electrode and the second contact electrode facing each other are parallel to side edges of the first pattern portion and the second pattern portion facing each other.

16. A method for fabricating a display device, comprising:
preparing a first electrode and a second electrode that are spaced apart from each other, a bank layer including a first barrier wall disposed on the first electrode and a second barrier wall disposed on the second electrode, and light emitting elements having ends disposed on the first electrode and the second electrode between the first and second barrier walls;
forming a contact electrode material layer disposed on the light emitting elements and the bank layer, an insulating material layer disposed on the contact electrode material layer, and a connection electrode material layer disposed on the insulating material layer;
patterning the connection electrode material layer and the insulating material layer to remove a portion overlapping the light emitting elements, and forming a connection electrode layer including connection electrodes spaced apart from each other, and an intermediate layer including pattern portions spaced apart from each other; and
patterning the contact electrode material layer using the connection electrode layer as a mask to form a contact electrode layer in contact with the light emitting elements and including contact electrodes spaced apart from each other.
