Abstract: A stretchable display device having a pliant substrate and a plurality of rigid substrates positioned on the first substrate spaced a first selected distance apart from each other. The pliant substrate having a having a first modulus of elasticity and the second substrates having a second modulus of elasticity that is greater than first modulus of elasticity. There is a semiconductor circuit have a semiconductor transistor and positioned on each of the rigid substrates. At least some of the rigid substrates also include an organic light emitting diode formed thereon. The pliant substrate is configured to stretch, moving the rigid substrates a second distance apart from each other that is greater than the first selected distance. Electrically conductive lines extend between respective ones of the second substrates, each of the electrically conductive lines being configured to stretch to maintain the rigid substrates electrically connected to each other when spaced the first distance apart from each other and also when they are spaced the second, greater distance from each other.
