Abstract
A power transmission device capable of adjusting a torque to be applied to an output shaft easily and removing a backlash between gears exactly, and a display device and a display panel pedestal that have the power transmission device. A power transmission deviceincludes a display panel, an output shaftto which the display panel is connected, output gearsandrotating integrally with the output shaft, transmission gearsandengaged with the respective output gears, motorsandproviding driving forces to the respective transmission gears, and a control circuitcontrolling the motors. The control circuitcauses the motorsandto rotate the transmission gearsandat different rotation numbers, and to transmit different driving forces to the respective output gearsand. The output shaftreceives not only a torque on a rotation direction side, but also a torque on a side opposite to the rotation direction, whereby the occurrence of play due to the direction change of a weight torque of the display panelis suppressed.
