The present invention discloses a packing box of liquid crystal panel. The packing box of liquid crystal panel comprises a box body, on at least two adjacent side walls of the box body respectively being provided with several grooves; the packing box further being provided with an elastic buffer part and a rigid part, the elastic buffer part being provided in the grooves, a first terminal of the elastic buffer part being close to the liquid crystal panel, there being a gap between the inner wall of the groove and a second terminal of the elastic buffer part, the rigid part being mounted on the groove through the position of the gap. In the packing box of liquid crystal panel, the content closely contacts with the packaging material, which avoids the displacement of the content generating secondary impacts during transportation and decreases the damages of the external impacts to the package.
