The embodiment of the invention provides a touch
display device, relates to the technical field of display, and is beneficial to narrow frame and light and thin design of the touch
display device while improving the binding reliability of a flexible touch circuit board and a touch substrate. The touch
display device comprises a display module, a touch substrate, a polaroid, an
adhesive film and acover plate which are sequentially arranged in the light emitting direction of the touch display device, the touch substrate comprises a touch area and a binding area, and the polaroid covers the touch area; the touch display device further comprises a flexible touch
control circuit board, the thickness of the flexible touch
control circuit board is smaller than that of the polaroid, the flexibletouch
control circuit board comprises a binding part and a bending part, and the flexible touch control circuit board is bound to the binding area through the binding part. A gap between the binding part and the first structure is filled with a filling structure, the filling structure and the
adhesive film are independent of each other, and the first structure is the structure, closest to the binding part, in the structure of the side, facing the light emitting direction, of the binding part.
