Claim 17:
18. A display device comprising:
a first substrate;
a first buffer layer on the first substrate;
an active layer of a transistor on the first buffer layer;
a first insulating layer on the active layer of the transistor;
a gate electrode of the transistor on the first insulating layer;
a second insulating layer on the gate electrode of the transistor;
a first planarization layer on the second insulating layer;
a first light emitting electrode on the first planarization layer;
a bank covering a part of the first light emitting electrode;
a light emitting layer on an exposed part of the first light emitting electrode that is not covered by the bank;
a second light emitting electrode on the light emitting layer and the bank;
a first inorganic layer on the second light emitting electrode;
a second substrate on the first buffer layer; and
a second buffer layer on the second substrate,
wherein the active layer of the transistor is on the second buffer layer,
wherein the first buffer layer comprises a first sub-buffer layer on the first substrate and a second sub-buffer layer on the first sub-buffer layer,
wherein the first sub-buffer layer is in contact with the first substrate in a transmissive area, and
wherein the transmissive area comprises a transmissive hole penetrating the bank, the first planarization layer, the second insulating layer, the first insulating layer, the second buffer layer, the second substrate, and the second sub-buffer layer.
