摘要: A stretchable substrate according to an embodiment of the present invention comprises a first modulus region which has a first modulus, a second modulus region which is located in a plane direction with respect to the first modulus region and has a second modulus higher than the first modulus, and a third modulus region which is located between the first modulus region and the second modulus region and has an interface modulus which gradually changes between the first modulus and the second modulus, wherein the interface modulus of the third modulus region may be constant in the thickness direction thereof.
