LCD panel packaging box

The invention discloses an LCD panel packaging box. The LCD panel packaging box comprises a frame body and a base plate, a step part is arranged on the inner side of the frame body, and at least two opposite ends of the base plate are overlapped on the upper surface of the step part. According to the LCD panel packaging box, the frame body and the base plate of the LCD panel packaging box are manufactured independently and then are combined for use, the base plate is overlapped on steps of the frame body for use, frame bodies and base plates in different packaging boxes can be generally used, after one part is damaged, only the damaged structure needs to be replaced, and thus the using cost is lowered. Meanwhile, the base plate can be thinned, a hollowed-out part or a groove can further be designed in the base plate, reinforcing ribs are arranged on the corresponding stressed part, the thickness of the base plate can be effectively decreased, and the weight of the packaging box is lowered. Meanwhile, the overall strength of the packaging box is guaranteed, raw materials can further be saved, and therefore the manufacturing cost is lowered.
