The present disclosure relates to a stretchable display device. According to an embodiment of the present disclosure, a stretchable display device includes a lower substrate having a plurality of first areas in which a plurality of sub-pixels is included, a plurality of second areas in which a plurality of connection lines is included, the connection lines electrically connecting adjacent ones of the first areas, and a plurality of third areas other than the first areas and the second areas. The stretchable display device further includes a plurality of additional sub-pixels in the respective third areas, and a plurality of piezoelectric patterns electrically connected to the respective additional sub-pixels. Adjacent ones of the first areas are spaced apart from one another. The stretchable display device may suppress deterioration of image quality when it is stretched.
