Abstract: Provided is a display device. The display device includes a stretchable display device. The stretchable display device includes a lower substrate including a display area and a non-display area. The stretchable display device further includes a plurality of lower connection lines on the lower substrate. The stretchable display device further includes a plurality of first substrates disposed on the display area, the plurality of first substrates defines sub pixels, and a modulus of the plurality of first substrates is larger than a modulus of the lower substrate. The stretchable display device further includes a plurality of connection substrates connecting adjacent first substrates among the plurality of first substrates. The stretchable display device further includes a plurality of upper connection lines disposed on the plurality of connection substrates. Therefore, various connection lines are configured in a limited space to improve an image quality of a stretchable display device.
