A flat panel display apparatus includes a main plate, an organic light
emitting element, a protecting layer and an attachable-detachable layer.
The organic light emitting element includes a first electrode, a second
electrode corresponding to the first electrode, and an organic light
emitting layer disposed between the first and second electrodes to
generate a light based on a current that flows between the first and
second electrodes through the organic light emitting layer. The organic
light emitting element is on the main plate. The protecting layer is on
the organic light emitting element to protect the organic light emitting
element. The attachable-detachable layer is on the protecting layer.
Therefore, an image display quality is improved, and a manufacturing cost
is decreased.
