Display device

A display device, comprising:

• a substrate;
• a first insulating layer on the substrate;
• first and second assembling wirings on the substrate;
• a second insulating layer disposed on the first and second assembling wirings and having a first hole and at least one or more second hole extending in a lateral direction of the first hole;
• a semiconductor light emitting device in the first hole;
• and
• a connection electrode in the second hole,
• wherein the second hole comprises:
• a second-first hole on the first assembling wiring;
• and
• a second-second hole on the second assembling wiring,
• wherein the connection electrode comprises:
• a first connection electrode disposed in the second-first hole;
• a second connection electrode disposed in the second-second hole;
• and
• a third connection electrode disposed along a perimeter of the semiconductor light emitting device within the first hole, and
• wherein each of the first and second connection electrodes comprises:
• a first connection region in contact with a side portion of the semiconductor light emitting device;
• a second connection region extending from the first connection region and contacting an upper surface of one of the first and second assembling wirings;
• and
• a third connection region extending from the second connection region and contacting an inner side surface of the second hole.
