Abstract: The present disclosure provides a stretchable display device. The stretchable display device including a plurality of first substrates which is disposed on a lower substrate to be spaced apart from each other and includes at least one pixel. The display device includes a plurality of connection substrates which connects adjacent first substrates among the plurality of first substrates. The display device includes a plurality of connection lines which electrically connects pads disposed on the plurality of adjacent first substrates and is disposed on side surfaces of the plurality of connection substrates. Therefore, a resistance of the connection line may be reduced or minimized.
