A bendable display device includes a display panel, a display circuit board having a first end thereof electrically connected to the display panel, a touch circuit board having a first end thereof electrically connected to the display panel, a support layer disposed on a surface of the display panel, and first and second heat dissipation layers. Each of the first heat dissipation layer and the second heat dissipation layer is disposed on a side of the support layer away from the display panel, and the first dissipation layer and the second dissipation layer are disposed on two sides of a bending area of the bendable display device. A second end of the display circuit board and a second end of the touch circuit board are respectively disposed on the first heat dissipation layer and the second heat dissipation layer. A connecting member for electrically connecting the first heat dissipation layer and the second heat dissipation layer is provided between the first heat dissipation layer and the second heat dissipation layer.
