at least one of a third organic layer and a third inorganic layer; and
at least one pair of conductive layers comprising a third conductive layer and a fourth conductive layer.
5. The display apparatus of claim 1 , wherein the display panel further comprises a plurality of organic light-emitting devices (OLEDs) spaced apart from each other.
6. A display apparatus, comprising:
a substrate;
a display panel disposed on a first side of the substrate;
an upper encapsulation film sealing the display panel; and
a lower encapsulation film disposed on a second side of the substrate, the second side of the substrate being opposite to the first side of the substrate,
wherein the upper encapsulation film comprises:
a first organic layer fully covering a top and sides of the display panel;
a first inorganic layer fully covering a top and sides of the first organic layer;
a second organic layer fully covering a top and sides of the first inorganic layer;
a first conductive layer fully covering a top and sides of the second organic layer and comprising an end extending therefrom to cover a portion of the substrate;
a second inorganic layer fully covering a top and sides of the first conductive layer, but not covering the end of the first conductive layer;
a second conductive layer disposed to cover only an uppermost top portion of the second inorganic layer;
a first additional electrode formed on the end of the first conductive layer; and
a second additional electrode formed on a top surface of the second conductive layer;
and
the lower encapsulation film comprises:
at least one of a lower organic layer and a lower inorganic layer, and
at least one pair of lower conductive layers comprising a first lower conductive layer and a second lower conductive layer.
7. The display apparatus of claim 6 , wherein the at least one of the lower organic layer and the lower inorganic layer is between the first lower conductive layer and the second lower conductive layer.
8. The display apparatus of claim 6 , wherein the first lower conductive layer or the second lower conductive layer is disposed on a first side of the at least one lower inorganic layer and the other of the first lower conductive layer or the second lower conductive layer is disposed on a second side of the at least one lower inorganic layer opposite to the first side.
9. A display apparatus, comprising:
a substrate;
a display panel disposed on an upper surface of the substrate; and
an encapsulation film disposed over the substrate and configured to seal the display panel, the encapsulation film comprising:
a first organic layer fully covering a top and sides of the display panel;
a first conductive layer fully covering a top and sides of the first organic layer and comprising an end extending therefrom to cover a portion of the substrate;
a first inorganic layer fully covering a top and sides of the first conductive layer, but not covering the end of the first conductive layer;
a second conductive layer disposed to cover only a top of the first inorganic layer, leaving sides of the first inorganic layer exposed;
a second organic layer covering a top of the second conductive layer to expose a side portion of the second conductive layer; and
a second inorganic layer covering a top of the second organic layer and exposing expose the side portion of the second conductive layer.
10. The display apparatus of claim 9 , wherein at least one of the first conductive layer and the second conductive layer comprise a transparent conductive oxide.
