In the first cutting, the supporting film 35 is firstly torn off, and then the base film 33, the adhesive film 31, and the display panel 10 are cut along the first cutting region 71 into a plurality of sub-display units 90. Because the base film 33 and the adhesive film 31 are hollowed in the first cutting area 71, the base film 33 and the adhesive film 31 do not need to be cut during the first cutting, and the cutting time and the cutting workload are saved. Because the adhesive film 31 and the base film 33 are hollowed out in a part of the second cutting area 73 and non-hollowed out in another part of the second cutting area, the adhesive film 31 and the base film 33 do not need to be cut for the second time in the hollowed-out area of the second cutting area 73, but need to be cut for the second time in the non-hollowed-out area, and damage to the display 19 caused by cutting in the second cutting area 73 is avoided to the greatest extent.

In the first cutting, the supporting film 35 is torn off, and then the base film 33, the adhesive film 31, and the display panel 10 are cut in the first cutting region 71 to form a plurality of sub-display units 90. Since the base film 33 and the adhesive film 31 are not hollowed out in the first cutting area 71, the base film 33 and the adhesive film 31 need to be cut simultaneously during the first cutting. Since the adhesive film 31 is hollowed out in the second cutting region 73, but the base film 33 is not hollowed out in the second cutting region 73, only the base film 33 needs to be cut when the second cutting is performed, and the display 19 is prevented from being damaged by the cutting in the second cutting region 73.
