1. A stretchable display device, comprising:
a lower substrate having thereon a display area including a plurality of pixels, a plurality of grip areas, and buffer areas positioned between the display area and the grip areas and adjacent to the plurality of grip areas;
a plurality of pixel substrates disposed in the display area, each of the pixel substrates being spaced apart from each other and being independently disposed;
a first base substrate disposed in each of the plurality of grip areas;
a second base substrate disposed in each of the plurality of grip areas;
a plurality of first connection lines disposed on each of the plurality of pixel substrates and extending between each of the plurality of pixel substrates in the display area, the plurality of first connection lines connecting the plurality of pixels formed on the plurality of pixel substrates;
a plurality of second connection lines disposed on the first base substrate and extending between the first base substrate to the second base substrate in each of the plurality of grip areas; and
a plurality of third connection lines disposed on the lower substrate in the buffer area, the plurality of third connection lines connecting the plurality of first connection lines and the plurality of second connection lines to each other, and having a ductile breaking rate higher than that of the plurality of first connection lines,
wherein the plurality of pixel substrates and the first and second base substrates are laterally spaced from each other do not overlap with each other from a plan view.
