There is provided a stand for a display device. The stand includes a base unit supporting the display device. A main link unit is hinged between the display device and the base unit. A pair of auxiliary links is eccentrically connected to hinges of the main link unit at different positions. A torsion spring includes at least one end connected to the pair of auxiliary links for applying an elastic force to the pair of auxiliary links. The main link unit has a smaller thickness, and thus the size of the stand can be reduced. The stand allows for convenient and smooth operation of the display device. Further, since the spring has a simple structure, the stand can be manufactured through a simple process with less cost. Furthermore, the outer appearance of the stand can be simple.
