1. A display device comprising:
a flexible substrate comprising a first organic layer, a second organic layer, and an inorganic layer sandwiched between the first organic layer and the second organic layer;
an organic light emitting diode device on the flexible substrate, the organic light emitting diode device comprising an anode, a cathode and an organic light emitting layer between the anode and the cathode; and
a flexible encapsulation layer on the organic light emitting diode device,
wherein a material of the first organic layer is the same as a material of the second organic layer,
wherein a thickness of the first organic layer is greater than a thickness of the second organic layer, and
wherein at least one of the first organic layer or the second organic layer comprises inorganic nano-particles.
