1. A flat display device, comprising:
- a base having a first fin;
a hinge assembly comprising a first friction piece and a second friction piece detachably disposed on a bolt and abutting each other; and
a panel having a first connection member bolted to the first fin by the hinge assembly, and rotating with respect to the base between a first position and a second position;
wherein the second friction piece has a groove, and the first friction piece has a protrusion restricted within the groove when the panel is rotated to any position between the first position and the second position.

Abstract
A flat display device (2) has a foldable base (25). The flat display device includes a flat panel (21) pivoted to a base by a hinge assembly (23). The panel is capable of rotating with respect to the base between a position and a second position. A third position of the panel with respect to the base is intermediate between the first position and the second position. A first friction force provided by the hinge assembly when the panel rotates between the first position and the third position is smaller than a second friction force provided by the hinge assembly when the panel rotates between the third position and the second position.
