Display device and method for manufacturing same, and multi-screen display device using same

A method of manufacturing a display device, the method comprising:

• forming a first wiring electrode at an upper surface of a first substrate to be connected to a plurality of semiconductor light emitting devices arranged in an array form on the upper surface;
• forming a first electrode pad connected to the first wiring electrode at an edge of the upper surface of the first substrate to be connected to the first wiring electrode;
• forming a side electrode at a side surface of the first substrate to have one end in contact with a side surface of the first electrode pad;
• bonding a second substrate to a lower portion of the first substrate;
• and
• forming a second wiring electrode at a lower surface of the second substrate,
• wherein an upper surface of the side electrode and an upper surface of the first electrode pad are positioned at substantially the same height,
• wherein a thickness of the first electrode pad is greater than a thickness of the first wiring electrode,
• wherein forming the side electrode further comprises forming the side electrode to have another end of the side electrode connected to the second wiring electrode, and
• wherein the side electrode comprises a bent portion between the one end and the another end of the side electrode to correspond to a lower edge of the second substrate.
