A flat panel display apparatus having a tilt/swivel mechanism therein allows a user to adjustably move the display panel in an up-and-down tilt direction and a right-and-left swivel direction along the connecting area. The flat panel display apparatus includes: a flat panel display, a computer, a swivel base, a yoke, a mounting base and a pair of elastic members. The yoke is pivotally secured to the connecting area of the flat panel display. The swivel base is pivotally secured to the flat panel display with the yoke. The swivel base has a first cylinder with two grooves parallel and opposite each other on the outer surface of the first cylinder. The mounting base is located in the computer. The mounting base has a second cylinder, the second cylinder having a cable hole formed at the center of the second cylinder to hold the swivel base and two mounting slots located in the cable hole opposite each other. Each elastic member has a projection to be held in the mounting slot. Each groove holds the projection and stops the swivel action while the swivel base swivels to a particular orientation in the mounting base.
