A hinge assembly ( 300 ) for use in a flat display monitor includes a support member ( 10 ), a rotational bracket ( 20 ) and a pivot mechanism ( 30 ) for rotatably connecting the rotational bracket to the support member. The support member includes an extending seat ( 16 ) defining a restricting groove ( 162 ) thereof. The pivot mechanism includes a pivotal shaft ( 301 ), a torsion spring ( 302 ), and a stop ( 303 ). The torsion spring is disposed around the pivotal shaft for providing torsion force. The pivotal shaft is fixedly connected to the rotational bracket and rotatably connected to the rotational bracket. The stop is fixed at end of the pivotal shaft and is rotatable in the restricting groove corresponding to rotation of the rotational bracket relative to the support member, with the stop being rotatable between a first utmost position and a second utmost position.
