The present disclosure relates to a packing box for liquid crystal glass panel, including: a box body, the side walls of which cooperate with each other to form a placement area used for placing the liquid crystal glass panel; a supporting member; and a mounting groove formed on the inner side of at least one side wall of the box body for receiving the supporting member, wherein a mounting part capable of forming a complementary shape fit with the mounting groove is formed on one end of the supporting member, and a supporting part extending toward the placement area is formed on the other end of the supporting member. The packing box is provided with the supporting member on the inner side of the side wall of the box body, in order to support and position the liquid crystal glass panel through the good structural strength of the supporting member itself. The supporting member cooperates with the side walls of the box body on the two sides thereof to form a holding area, for placing the chip on film of the liquid crystal glass panel. Therefore, the chip on film can be out of contact with the packing box, thus providing better protection for the liquid crystal glass panel.
