Claim 0:
1. A stretchable display device comprising:
a stretchable substrate including a pixel area and a non-pixel area;
pixel units provided on the pixel area of the substrate;
bank units provided on the non-pixel area of the substrate; and
a sealing layer covering the pixel units,
wherein the substrate comprises a substrate polymer with a polar functional group, the sealing layer comprises a sealing polymer with a polar functional group, and the bank units comprise a bank polymer;
a substrate composite of an inorganic compound and the substrate polymer is provided in the pixel area of the substrate, wherein the inorganic compound penetrates into the pixel area and binds to the polar functional group of the substrate polymer, and
a sealing composite of the inorganic compound within the sealing polymer, wherein the inorganic compound binds to the polar functional group of the sealing polymer,
wherein an amount of the inorganic compound in the bank unit is lower than an amount of the inorganic compound in the sealing layer.
