Display device and manufacturing method of the same

A display device comprising:

• a substrate;
• a plurality of first internal banks disposed on the substrate and having an inclined side surface and a top surface;
• a plurality of second internal banks disposed on the substrate, having an inclined side surface and a top surface, and spaced apart from the plurality of first internal banks, respectively;
• a plurality of first alignment electrodes respectively disposed on the plurality of first internal banks;
• a plurality of second alignment electrodes respectively disposed on the plurality of first internal banks and spaced apart from the plurality of first alignment electrodes, respectively;
• a plurality of light emitting elements disposed between the plurality of first alignment electrodes and the plurality of second alignment electrodes;
• a plurality of first connection electrodes in contact with first end portions of the plurality of light emitting elements, the plurality of first connection electrodes overlapping the plurality of first alignment electrodes, respectively;
• a plurality of second connection electrodes in contact with second end portions of the plurality of light emitting elements, the plurality of second connection electrodes overlapping the plurality of second alignment electrodes, respectively, and spaced apart from the plurality of first connection electrodes, respectively;
• and
• an insulating layer disposed between portions of the plurality of first connection electrodes which overlap the top surfaces of the plurality of the first internal banks and portions of the plurality of first alignment electrodes which overlap the top surfaces of the plurality of the first internal banks, wherein
• each of the plurality of first connection electrodes has a first edge overlapping a corresponding one of the plurality of light emitting elements and a second edge opposite to the first edge thereof in a plan view,
• each of the plurality of second connection electrodes has a first edge overlapping a corresponding one of the plurality of light emitting elements and a second edge opposite to the first edge thereof in a plan view,
• the first and second edges of each of the plurality of first connection electrodes in a plan view are disposed inwardly from an edge of each of the plurality of first alignment electrodes, respectively, in a plan view, and
• the first and second edges of each of the plurality of second connection electrodes in a plan view are disposed inwardly from an edge of each of the plurality of second alignment electrodes, respectively, in a plan view.
