Abstract: A stretchable display devices includes a flexible substrate. A plurality of first substrates and a plurality of second substrates are disposed on the substrate. The plurality of first substrates are spaced from each other and the plurality of second substrates, and the plurality of second substrates are spaced from each other. A plurality of connection supports are coupled to the plurality of first and second substrates. Connection lines extend on the plurality of connection supports to form an electrical connection between the plurality of first substrates and the plurality of second substrates. A distance between one of the plurality of second substrates and a corresponding outer one of the plurality of first substrates is greater than a distance between the plurality of first substrates to reduce stress on the plurality of second substrates during bending or stretching of the display device.
