Abstract: Disclosed herein are a stretchable display panel and device and a manufacturing method thereof. The stretchable display panel comprises: a lower substrate having an active area and a non-active area surrounding the active area; a plurality of individual substrates disposed on the lower substrate and located in the active area; a plurality of pixels disposed on the plurality of individual substrates; and a connection line disposed between the plurality of individual substrates and the lower substrate, wherein the modulus of the plurality of individual substrates is higher than that of at least one part of the lower substrate, and wherein the connecting line extends to the bottom surface of the individual substrates, such that the connecting line electrically connects a pad disposed on the individual substrates without a step in the top surface of the connecting line. That is, the connecting line has a uniform height from the lower substrate for its entire length. Accordingly, the stretchable display device according to the present disclosure may reduce damage to the connecting line due to a step of the connecting line, so reliability of the stretchable display device may be improved.
