Abstract: 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.

Abstract: According to an aspect of the present disclosure, a stretchable display device includes a lower substrate. A plurality of first substrates is disposed on the lower substrate and includes a plurality of pixels, and a plurality of connection lines electrically connects the plurality of pixels. A plurality of heat transfer lines overlap the plurality of connection lines, and a heat radiator is exposed to the outside and overlaps the plurality of connection lines and the plurality of heat transfer lines. By doing this, a heat radiation efficiency of the stretchable display device may be improved.
