To solve the above problem, embodiments of the present disclosure provide a buffer device 300 that can facilitate the manufacturing of a display device.

Fig. 2 is a schematic structural diagram illustrating a bar-shaped buffer device according to an exemplary embodiment, and fig. 3 is a schematic structural diagram illustrating a buffer device according to an exemplary embodiment. As shown in fig. 2 and 3, the buffering device 300 may be applied to a display apparatus, disposed around a display panel, for supporting the display panel. The cushioning device 300 includes a first cushioning member 301 and a second cushioning member 302.

And the flexibility of the first buffer component enables the buffer device to be arranged between the display panel and other components in a clamping mode, so that the manufacturing mode of the display device is optimized.

In addition, the second supporting member has a higher rigidity than the first supporting member, and various ways may be adopted in the process of disposing the buffer device around the display panel, for example, the side surface of the display panel may be first combined with the second supporting member. In some embodiments, the display panel and other related components may be combined first, and a certain space is left between the side surface of the display panel and the related components to mount the buffer device. In such a process, the rigidity of the second support member can protect the cushioning device itself from damage, and also helps to maintain the shape of the cushioning device so that the cushioning device can act on the display device in this space and can be pressed into the display device to complete the manufacturing process.

In the disclosed exemplary embodiment, the second cushioning member 302 is provided with a plurality of through grooves 321.
