The present invention provides a display panel storing device, having a framework; two support frames, which are opposite to each other and slidably connected to the framework, for supporting a display panel therebetween; and a driving unit for driving the two support frames to move towards or away from each other to change the distance between the two support frames. The display panel storing device can simplify the adjustment procedure, increase efficiency, and reduce manpower cost, and is unnecessary to detect the symmetry of the two support frames.
