As shown in FIG. 9C, the partition plate 210 includes a plate body 211 and a first protruding portion 212. In one embodiment, the plate 211 may have a rectangular shape, but the invention is not limited thereto. The plate body 211 has first and second side edges 211s1 and 211s3 opposite to each other, and second and fourth side edges 211s2 and 211s4 opposite to each other. The first protruding portion 212 is connected to the plate body 211 and protrudes from one side (for example, the first side 211s1), and protrudes beyond the side of the optical film 10 (such as the fourth side 10s4), as shown in FIGS. 9A and 9B. . In this way, the first protruding portion 212 protruding from the optical film 10 can be easily grasped by the operator, so as to facilitate the placing and placing of the optical films 10.

In one embodiment, the plate body 211 and the first protruding portion 212 can form an integrated structure in the same process. The aforementioned process is, for example, punching or cutting. In another embodiment, after the plate body 211 and the first protruding portion 212 are formed separately, the connection plate 210 is connected by any connection method. The connection method is, for example, adhesion. In one embodiment, the materials of the plate body 211 and the first protruding portion 212 may be the same or different. The material of the plate body 211 and the first protruding portion 212 can be made of polypropylene (PP), polystyrene (PS), cardboard, corrugated paper, cardboard or acrylic.

In this embodiment, as shown in FIG. 9C, the first protruding portion 212 is a polygon, such as a quadrangle.

In this way, it is possible to prevent the surrounding members 110a and 110b from being interfered by the plate body 211, and to be able to closely adhere to the optical film 10, thereby more stably fixing the relative positions of the optical films 10.

In this embodiment, the first protrusions 212 of the spacers 210 do not overlap each other. For example, as shown in FIG. 9B, the first protrusions 212 of the spacers 210 are staggered from each other in a direction (such as the x direction) perpendicular to the stacking direction (such as the z direction) of the optical films 10, and so It is possible to prevent the operator from being interfered by the other first protrusions 212 when grasping one of the first protrusions 212.

As shown in FIG. 9A, an end portion of the first protruding portion 212 of the partition plate 210 faces the fourth side wall 225 of the carrier box 220. In an embodiment, the first distances D1 between the ends of the first protruding portions 212 of the spacers 210 from the fourth side wall 225 may be the same or different, and the embodiment of the present invention is not limited thereto. In this embodiment, a first distance D1 between an end of the first protruding portion 212 of each of the partition plates 210 and the fourth side wall 225 is different. For example, the lengths of the first protrusions 212 of the spacers 210 are different, and the spacers 210 are arranged in such a manner that the first protrusions 212 of the spacers 210 become shorter from the bottom wall 221 upward, so that the first distances D1 from The bottom wall 221 becomes longer in the upward direction. In this way, the upper first distance D1 is longer than the lower first distance D1, so that when the operator grasps the first protruding portion 212 from the top to the bottom, the operator is interfered by the first protrusions 212 with a small or minimum number. In another embodiment, based on different considerations, these first distances D1 may be gradually shortened from the bottom wall 211 upward; or, these first distances D1 may be arbitrarily changed, and are not limited to being gradually shorter or longer. . In addition, the smaller the size of the optical film 10 is, the longer the first distance D1 can be. For example, when the size of the optical film 10 is 15.6 inches, the length of the long side of the optical film is about 350 mm, and the first distance D1 is, for example, between about 15 mm and about 25 mm; when the size of the optical film 10 is When the length is 14 inches and the length of the long side of the optical film is about 315 mm, the first distance D1 can be increased to be, for example, between about 50 mm and about 60 mm.

As shown in FIG. 9A, there is a second distance D2 between the optical film 10 and the fourth side wall 225. The ratio between the first distance D1 and the second distance D2 is between 0.3 and 0.5. In this way, the first protruding portion 212 can be prevented from being too close to the fourth side wall 225, thereby avoiding excessive interference by the operator in the process of grasping the first protruding portion 212.
