In addition, the vacuum region 111 includes a plurality of first vacuum tubes 111a and a plurality of second vacuum tubes 111b.

The seating groove 112 is a depressed portion corresponding to a region where the mold frame F is seated on the rim of the attracting frame 110. That is, the mold frame F stably stays in the seating groove 112 formed along the rim of the suction frame 110.

The depressed portion 114 is a portion formed inwardly from the outer edge of the rim of the riding groove 112 which is a rim region of the suction frame 110, Spaced apart from each other. The cavity 114 is formed with a first suction hole 115 communicating with the vacuum region 111 to suction the mold frame F. Similarly to the suction groove 112, And the second suction holes 113 to be adsorbed by the mold frame F may be formed in a direction orthogonal to the first suction holes 115.

3, since the first suction hole 115 is connected to the first vacuum tube 111a which communicates with one side of the vacuum region 111, vacuum force is applied from the vacuum generator, have. Since the second suction hole 113 is connected to the second vacuum tube 111b branched from the first vacuum tube 111a in a direction orthogonal to the first vacuum tube 111a, So that the adsorbing force can be exerted.

Since the first suction holes 115 are connected to the first vacuum tube 111a, it is preferable that the first suction holes 115 are formed in a corresponding number to the first vacuum tube 111a. Likewise, It is preferable to provide the number corresponding to the second vacuum tube 111b in order to be connected to the second tube 111b.

3, since a flexible substrate to which an LED is to be attached is attached to one side of the mold frame F in a process of assembling the backlight unit among the mold frames F to be mounted in the mounting grooves 112, The groove 112 is provided not only with the first suction hole 115 but also with the second suction hole 113 at one side so that the mold frame F and the flexible substrate are fixed by suction with the first suction hole 115, Allows seating.

As shown in FIGS. 1 and 2, the base frame 120 may have a rectangular plate shape having four sides.
