When the display panel 11 is a flexible display panel, the bottom plate 21 can support the flexible display panel and maintain the position of the display panel 11.
In some embodiments, the display panel 11 is a flexible display panel that can be bent to meet the user's usage. In order to realize the bendable performance of the display panel 11, in some embodiments, the display panel 11 includes a folding region 101, the number of the middle frame assemblies 20 is two, the two middle frame assemblies 20 are respectively connected to different portions of the display panel 11, optionally, the two middle frame assemblies 20 are respectively connected to portions outside the folding region 101, so as to prevent from affecting the folding of the display panel 11, at this time, the display device 100 further includes a rotating shaft assembly 40, the rotating shaft assembly 40 is correspondingly disposed in the folding region 101, and the rotating shaft assembly 40 rotatably connects the two middle frame assemblies 20 to drive the display module 10 to bend.

Through the above arrangement, the first clamping piece 220 and the second clamping piece 230 which are detachably connected are mutually matched to stably clamp and connect the cover plate layer 12, and the integrally formed clamping structure 22 is prevented from being connected with the cover plate layer 12 due to manufacturing errors and other factors.
