1. A display device, comprising:
a stretchable lower substrate;
a plurality of first substrates disposed on the stretchable lower substrate and including a first pixel and a second pixel;
a plurality of second substrates configured to couple first substrates adjacent to each other among the plurality of first substrates;
a plurality of connection lines disposed on the plurality of second substrates, configured to couple the first pixel and the second pixel and including a metal material,
the plurality of connection lines including a plurality of first connection lines extended in a first direction and electrically connecting at least one of the first pixel and the second pixel of the first substrates adjacent to each other in the first direction, a plurality of second connection lines extended in a second direction and electrically connecting at least one of the first pixel and the second pixel of the first substrates adjacent to each other in the second direction, and a plurality of third connection lines extended in a third direction and electrically connecting at least one of the first pixel and the second pixel of the first substrates adjacent to each other in the third direction; and
an upper insulating layer disposed between a first layer where the plurality of first connection lines and the plurality of second connection lines are disposed and a second layer where the plurality of third connection lines,
wherein the plurality of first connection lines and the plurality of second connection lines are disposed on a same layer,
wherein the plurality of third connection lines is disposed on a different layer from the plurality of first connection lines and the plurality of second connection lines,
wherein the plurality of first connection lines and the plurality of second connection lines contact a bottom surface of the upper insulating layer, and
wherein the plurality of third connection lines contacts a top surface of the upper insulating layer.
