Abstract

Provided is a supporting apparatus for a display device. The supporting apparatus includes a stationary unit fixed at a fixing location, a device supporting unit supporting the display device, a connection unit connecting the stationary unit to the device supporting unit and guiding motion of the device supporting unit, and a tilting frictional unit interposed between the connection unit and the device supporting unit and guiding tilting motion of the device supporting unit in a vertical direction. The tilting frictional unit includes a first arc member fixed to the connection unit and a second arc member fixed to the device supporting unit. The first and second arc members contact each other to generate frictional force.

Claims
