Abstract: A sliding mechanism and a display device using the same are provided. The display device is supported by a supporting structure. The sliding mechanism comprises a sliding track, a slider, an elastic element and a fixing prop. The sliding track is disposed on the display device. The slider is movably disposed on the sliding track. The elastic element has a winding portion disposed at one end of the sliding track and an extended end connected to the slider and simultaneously movable with the slider. The fixing prop is disposed on the slider for connecting the slider with the supporting structure. When the slider slides along the sliding track, the display device moves relative to the supporting structure for adjusting the height of the display device accordingly. The elastic element provides the slider with a constant force whose direction is opposite to that of the gravity of the display device.
