(2) The prior art heat treatment device is composed of a heating device that heats the display panel and a cooling device that cools the display panel after heat treatment. In the heating device and the cooling device, a support member for supporting the display panel is used. In order to prevent the display panel from being damaged, the support area of the support panel for the display panel is made as small as possible. Therefore, it is known to have a support such as a pin at a plurality of locations of the display panel (for example, refer to Patent Document 1). ). However, with this support method, the load on the display panel is concentrated on the pins and the like. When a load is generated, there is a problem that the display panel is deflected. The display panel is deflected to produce a display spot. Therefore, it is considered that the contact area with the display panel is made large. In the cooling device in which the contact area with the display panel is made large, as shown in Fig. 10, 'a predetermined number of horizontal elongated support members S (only one shown) and the citrus neighbors are spaced apart from each other by 0. Further, they are arranged in parallel, and the upper surface of each of the support members is formed by a flat support surface. When the display panel is supported by the support member, the problem of the display spot caused by the load concentration can be eliminated. However, as shown in Fig. 1, heat transfer occurs at the contact portion (point A) between the display panel and the support member, and the display panel 1255571 can rapidly cool the display panel to a portion other than the other (point B). The cooling rate in the (: point) is lowered. Therefore, when a temperature difference occurs in the cooling curves of the two parts, the same display spot is generated similarly to the case of the load difference. [Patent Document 1] Japan Special Open 2002 - 1 3 09 5 9 (3) SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] An object of the present invention is to provide a cooling device having a support device for supporting a display panel when the display panel is cooled, and the above-described The display spot caused by any one of the load difference and the temperature difference does not occur. [Means for Solving the Problem] The cooling device for the display panel of the present invention includes a cooling chamber and a display panel provided in the cooling chamber. a support device supported by a plurality of segments, the support device having a support member having a partial contact with the display panel to support the display panel The support portion and the support portion are brought into contact with different portions of the display panel as time passes. In the cooling device for the display panel of the present invention, the contact portion between the display panel and the support member passes over time. At the same time, the position of the heat transfer of the display panel by the contact portion is changed, so that the temperature difference can be prevented from being generated on the display panel. Further, the support member is mounted on the horizontal rocking shaft to support When the arc-shaped support surface centered on the axis of the rocking shaft is formed, 'the display panel moves toward the horizontal direction as the rocking shaft rotates'-the contact surface is in contact with the different parts of the display panel. The -6- 1352571-shaped rocking shaft 81 and the supporting member 82 attached to each of the rocking shafts 81 and the rocking shaft 81. Each of the supporting members 82 is concentric with the corresponding rocking shaft 81, and the outer peripheral surface is made In the case where the shed 71 is used for the cylindrical drum supporting the surface 83, in the vicinity of each of the support members 82, each member 82 becomes a flow which blocks the cooling wind, and It flows to the surface of the display W. Therefore, there is fluidity in the vicinity of each support member 82. To prevent this phenomenon, a filter 84 is disposed on each of the sheds 71, but the wind is in a direction orthogonal to the sheds 71. The upper flow is preferably the same. The localized prevention of the shaking cycle and the thermal movement of the rocking shaft 81 is the same as that of the embodiment described above. The seventh and eighth drawings show a modification of the other shed 91. The shed 91 has support pieces 101 and 102 which are juxtaposed in the front-back and left-right directions and which are adjacent to each other and are paired with each other in pairs. The pair of branches 101 and 102 can be lifted and lowered individually. The upper end of 102 has horizontal flat support faces 103, 104. On the upper shelf 91, one of the pair of support sheets 101, 102 is raised, and the other side 1 is lowered. The rising support piece 10 support surface 103 is in contact with the lower surface of the display panel W. As described above, as shown in the middle shed 91, the support faces 103, 104 of the support pieces 1?1, 1?2 when the other support piece 102 are raised are simultaneously brought into contact with the lower surface of the display panel W. Then, as shown in the following section 91, when one of the holding pieces 101 is lowered, only the supporting surface of the other supporting piece 102 comes into contact with the lower surface of the display panel W. The number of the configuration support panels may be used for cold use. In the example, the holding sheets are formed in a state of 10 1 1 , and the dual-purpose surface supports 104 1352571. Therefore, the support surface 103 of one of the support sheets 101 is in contact with the display panel w, and both sides In the case where the support faces 103, 104 of the support sheet 101' 102 are in contact with each other and the support surface 104 of the other support sheet 102 is in contact, the contact portions of the display panel W and the support sheets 101, 102 are changed in three ways. Therefore, the concentration of thermal movement can be avoided. In the above, the number of the sheds, the number of the rocking axes, the number of the supporting members attached to the respective rocking shafts, and the like can be arbitrarily selected. Further, although the cooling chamber has the inlet and the outlet of the display panel, one opening may be used as the entrance and exit. Further, although the cylindrical drum is continuously continuous over the entire length of the rocking shaft, it may be a discontinuity.
