A liquid crystal panel packing box and a liquid crystal panel packing method are provided. The packing box is equipped with an elastic retractable member assembled in an accommodating groove thereof. The elastic retractable member is memory metal and can generate stretching and retracting effects with the change of temperature to thereby fix liquid crystal panels disposed in the packing box. Accordingly, in the processes of packing and transporting the liquid crystal panels, the seamless assembling between the liquid crystal panels and the packing box is realized, the damage caused by collision between edges of the liquid crystal panels and a box body of the packing box is avoided, the secondary impact generated resulting from the shift of the liquid crystal panels is eliminated and the safety is improved consequently.
