Abstract
The present disclosure relates to a stretchable display device. The stretchable display device includes a lower substrate, a plurality of pixel substrates which is disposed on the lower substrate to be spaced apart from each other, a plurality of first power lines disposed on the plurality of pixel substrates, a plurality of second power lines disposed on the plurality of pixel substrates, a plurality of driving transistors which is disposed on the plurality of pixel substrates and is electrically connected to the plurality of second power lines, and a plurality of light emitting diodes which is disposed on the plurality of pixel substrates and includes an anode electrically connected to the plurality of first power lines and a cathode electrically connected to the plurality of driving transistors. Accordingly, instead of the driving transistor, the anode of the light emitting diode is directly connected to the first power line to achieve a common anode structure, thereby reducing or minimizing fluctuation of the gate-source voltage Vgs of the driving transistor.
