Claim 18:
19. A display device comprising:
a first base substrate;
a first barrier layer disposed on the first base substrate;
a second base substrate disposed on the first barrier layer;
a first sub-substrate disposed on the second base substrate and comprising at least one dopant selected from a group consisting of: fluorine (F), boron (B), arsenic (As), phosphorus (P), chlorine (Cl), bromine (Br), iodine (I), astatine (At), sulfur (S), selenium (Se), argon (Ar), and tellurium (Te);
a second barrier layer disposed on the first sub-substrate;
a second buffer layer disposed on the second barrier layer;
a first buffer layer disposed on the second buffer layer;
at least one transistor disposed on the first buffer layer; and
an organic light-emitting diode disposed on the at least one transistor,
wherein the first sub-substrate is in contact with the second barrier layer,
wherein a dielectric constant and a specific resistance of each of the first sub-substrate and the second barrier layer satisfy the following relational expression:

ε1p1≠ε2p2 

wherein ε1 denotes the dielectric constant of the first sub-substrate, p1 denotes the specific resistance of the first sub-substrate, ε2 denotes the dielectric constant of the second barrier layer, and p2 denotes the specific resistance of the second barrier layer.
