<p>PURPOSE: A flat panel display device prevents damage to a flexible circuit board by forming the flexible printed circuit board inside a panel. CONSTITUTION: A first substrate (110) includes a display part (120) displaying images and a terminal part (130) disposed on the outer side of the display part. A second substrate (140) is disposed on one surface of the first substrate to cover the display part. A flexible printed circuit board (150) is extended to the outside of the second substrate by being connected to the terminal part. The flexible printed circuit board includes a bent part (153) bent between the terminal part and the second substrate. A circuit board (170) supplies a data signal to the first substrate.</p>
