Since the contact area of the mold frame F is narrower than the contact area of the reflective sheet S bonding surface, the interval of the plurality of first suction holes 112C is smaller than the interval of the plurality of second suction holes 114B At this time, the diameter of the first suction holes 112C may be smaller than the diameter of the second suction holes 114B.

On the other hand, the first position 112 and the second position 114 may have mutually intersected regions as shown in FIG.

Here, a portion of the second flow path 114A may be formed to have a height different from that of the first flow path 112B, so that the first position 112 and the second position 114 intersect each other The first flow path 112B and the second flow path 114A are not connected to each other and can have independent internal spaces so that the first suction hole 112C and the second suction hole 114B are The mold frame F inserted in the insertion groove 112A and the mold frame F bonded with the reflection sheet S positioned in the second position 114 can be individually attracted and fixed.
