1st mounting parts

11 and 12 are curved in the direction on the opposite side to the expansion-

contraction shafts

15 and 16, the expansion-

contraction shafts

15 and 16 do not become obstructed when making the display panel 1 into a required bending state.

The first mounting

portions

11 and 12 are adjusted so that the curved state is about R2000. Note that the degree of curvature of the display panel 1 can be finely adjusted by changing the suction position of the suction pad 2.

Then, as shown in FIG. 4, the display panel 1 sucked by the suction pad 2 is placed on the placement portion. In this case, since the

first placement portions

11 and 12 are curved to the same extent as the display panel 1, the display panel 1 can be placed without any stress acting on the display panel 1. Thereafter, the display panel 1 is fixed to the mounting unit 10 with the

brackets

20 and 21, and the suction pad 2 is removed.

FIG. 5 is an explanatory view showing an example in which the display panel 1 is bent into a required bending state by the mounting unit 10 of the present embodiment. As described with reference to FIG. 2, the drive shaft 19 is rotated by bringing a predetermined tool (for example, a driver) into contact with the groove 183 and transmitting a rotational force to the groove 183. In conjunction with the rotation of the drive shaft body 19, the inner shaft body 162 enters the outer cylinder shaft body 161, and the telescopic shaft body 16 becomes shorter.
