[0035] Specifically, the opening region 12 is provided with a plurality of opening structures 13, one of the plurality of opening structures 13 is arranged at the position of one of the plurality of electronic devices 5 in the aggregation region, and the opening structure 13 is arranged at the position of the electronic device 5 in the corresponding aggregation region to avoid the electronic device 5 in the aggregation region causing the reflective film 1 to bulge and bump.

[0036] Further, the opening operation is performed at the position of the electronic device 5, so that the opening structure 13 in the opening region 12 can be accurately arranged at the position of the electronic device 5, the precise tensile stress of the reflective film 1 at the position of the electronic device 5 can be released, and the reflective film 1 is more attached to the lamp panel 2 and the electronic device 5 on both sides.
