ABSTRACT:
A flat panel display comprises: a transparent substrate having a first display portion and a second display portion; at least one first organic light emitting diode positioned in the first display portion for emitting light in a first direction perpendicular to the transparent substrate, and having a first lower electrode, a first upper electrode, and a first organic emission layer interposed between the first lower electrode and the first upper electrode; and at least one second organic light emitting diode positioned in the second display portion for emitting light in a second direction opposite to the first direction, and having a second lower electrode, a second upper electrode, and a second organic emission layer interposed between the second lower electrode and the second upper electrode. As a result, the flat panel display is fabricated using one substrate to display both screens such that one of the screens is displayed while the other is not displayed. Accordingly, the thickness of electronic equipment employing the flat panel display may be reduced, and the power consumption of the electronic equipment may also be reduced.
