It is noted that the number of edge-carrying regions 22 may be one, two, four or even more. When the number of the edge bearing areas 22 is one, the edge of the edge bearing area 22 far from the center bearing area 21 is protruded from the edge of the corresponding side of the adhesive layer 12, and when the number of the edge bearing areas 22 is at least two, at least one edge bearing area 22 of the at least two edge bearing areas 22 is protruded from the edge of the corresponding side of the adhesive layer 12.
