first and second coupling parts along opposing sides of the cavity for securing a plurality of liquid crystal cells therebetween; and a cover for covering the box, the box and the cover being made of a resin material, wherein the first and second coupling parts include a plurality of protrusions, wherein each of the protrusions includes a first surface being substantially parallel to an edge of the box and a second surface being inclined with respect to the same edge of the box, wherein four of the coupling protrusions that are closest to the edge of the box have a larger width than other coupling protrusions. ### Claim 2 (depends on 1) The liquid crystal cell carrying case according to claim 1, wherein the resin includes one of a polyethylene-based resin, a polypropylene-based resin and a combination thereof. ### Claim 3 (depends on 1) The liquid crystal cell carrying case according to claim 1, wherein an inner portion of the box is made of a polyethylene-based resin, and an outer portion of the box is made of a polypropylene-based resin. ### Claim 4 (depends on 1) The liquid crystal cell carrying case according to claim 1, wherein an inner portion of the cover is made of a polyethylene-based resin, and an outer portion of the cover is made of a polypropylene-based resin. ### Claim 5 (depends on 1) The liquid crystal cell carrying case according to claim 1, further comprising a pad at a bottom surface of the cavity. ### Claim 6 (depends on 5) The liquid crystal cell carrying case according to claim 5, wherein the pad is detachably installed at the bottom surface of the cavity. ### Claim 7 (depends on 1) The liquid crystal cell carrying case according to claim 1, further comprising a rubber band formed along an upper circumference of the box, the rubber band attaching the box and the cover to each other. ### Claim 8 (depends on 1) The liquid crystal cell carrying case according to claim 1, wherein the first and second coupling parts have alternative concave-convex shapes. ### Claim 9 (depends on 1) The liquid crystal cell carrying case according to claim 1, further comprising a plurality of belt grooves on outer surfaces of the box and the cover. ### Claim 10 (depends on 1) The liquid crystal cell carrying case according to claim 1, further comprising a plurality of vacuum grooves on an upper surface of the cover. ### Claim 11 A liquid crystal cell carrying case comprising: a box having a cavity; first and second coupling parts along opposing sides of the cavity for securing a plurality of liquid crystal cells therebetween, the first and second coupling parts being integrally formed with the box as a single body, each of the first and second coupling parts including a plurality of protrusions, each of the protrusions having a first surface being substantially parallel to an edge of the box and a second surface being inclined with respect to the same edge of the box; and a cover for covering the box, wherein four of the coupling protrusions that are closest to the edge of the box have a larger width than other coupling protrusions. ### Claim 12 (depends on 11) The liquid crystal cell carrying case according to claim 11, wherein the box and the cover include one of a polyethylene-based resin, a polypropylene-based resin and a combination thereof. ### Claim 13 (depends on 11) The liquid crystal cell carrying case according to claim 11, wherein inner portions of the box and the cover are made of a polyethylene-based resin, and outer portions of the box and the cover are made of a polypropylene-based resin. ### Claim 14 (depends on 11) The liquid crystal cell carrying case according to claim 11, further comprising a rubber band formed along an upper circumference of the box, the rubber band attaching the box and the cover to each other. ### Claim 15 (depends on 11) The liquid crystal cell carrying case according to claim 11, further comprising a pad at a bottom surface of the cavity. ### Claim 16 (depends on 11) The liquid crystal cell carrying case according to claim 11, further comprising a plurality of belt grooves on outer surfaces of the box and the cover. ### Claim 17 (depends on 11) The liquid crystal cell carrying case according to claim 11, further comprising a plurality of vacuum grooves on an upper surface of the cover.
