る。On both longitudinal sides of a flexible liquid crystal display panel 1 made of a flexible material, two rod-shaped connecting members 2 for rotatably holding the liquid crystal display panel 1 are provided. Nuts 3a and 3b, each having a reverse thread, are attached to both ends of each of the two connecting members 2. Two screw shafts 4 having the same pitch as the nuts 3a and 3b are threaded so as to extend between the two nuts 3a and 3b.
3b, and provided on the upper and lower sides in the longitudinal direction of the liquid crystal display panel 1. The two screw shafts 4 obtain rotational force by a motor 9 as a driving source via gears 6, 8 and a belt 7, respectively. The center of the rear surface of the liquid crystal display panel 1 can be slid in the direction of arrow D by being guided by a guide 5 provided on the housing 10 side.

The power is transmitted to the screw shaft 4 via the belt 7 and the gear 6. Screw shaft 4
When the nut rotates, the nuts 3a and 3b screwed thereto move in opposite directions to each other because the nuts are reversely threaded. If the screw shaft 4 is rotated in the direction of the arrow C shown in FIG. 2C and the nut 3a is moved in the direction of the arrow A in a thread cutting relationship, the other nut 3b is reverse-threaded and is shown in FIG. As shown in the drawing, the nuts move in the direction of arrow B, and eventually the two nuts 3a and 3b move in directions approaching each other.

湾曲中心がずれなくなり、左右均一で連続的な湾曲形状
が得られる。As a result of this approaching movement, the liquid crystal display panel 1 via the connecting member 2 is curved in an arc shape as shown in FIG. At this time, since the center of the back surface of the liquid crystal display panel 1 is slidably fitted to the guide 5, the guide 5 plays a role of restricting the movement of the center of the liquid crystal display panel 1 in the left-right direction,
The center of curvature does not shift, and a continuous curved shape that is uniform left and right is obtained.
【００１５】左右のナット３ａ，３ｂの接近距離が近づ

晶表示板１とすることもできる。When the screw shaft is further rotated after the center of the rear surface of the liquid crystal display panel 1 contacts the guide 5, the distance between the left and right nuts 3a and 3b is further reduced, and the liquid crystal display panel 1
Of the vicinity of the center becomes almost flat due to the presence of the guide 5,
The liquid crystal display panel 1 may be curved only in the vicinity of the left and right ends, and have a bend close to a cross-sectional shape as if a small bowl of tableware was turned down.
