A hinge assembly ( 100 ) for use in a flat display monitor ( 120 ) includes a base seat ( 10 ), a pivotal shaft ( 20 ) and a plurality of washers ( 30, 40, 50, 60, 70 ). The base seat includes a first end portion ( 12 ) and a second portion ( 14 ), which are substantially perpendicular to each other. The first end portion has a retaining hole ( 122 ) therein. A protrusion ( 124 ) of the first end portion extends into the retaining hole. The pivotal shaft includes a pivotal portion ( 24 ). The pivotal portion has at least one flat surface ( 242 ) pivotally engaging with the protrusion. The pivotal shaft passes through the retaining hole of the base seat and the plurality of washers, allowing the elements of the hinge assembly to be fastened together.
