Claim 17:
18. A display device, comprising:
a display panel;
a touch panel, disposed on a display side of the display panel;
a polarizer, disposed on a side, distal from the display panel, of the touch panel; and
a touch flexible printed circuit board, comprising a first portion, a second portion and a bending portion connecting the first portion and the second portion; wherein the first portion is disposed on a side, distal from the display panel, of the touch panel, the second portion is disposed on a non-display side of the display panel, the first portion is provided with a first connection terminal, and the touch panel is provided with a second connection terminal, the first connection terminal being electrically connected to the second connection terminal,
wherein an orthographic projection of the polarizer on a reference plane falls outside an orthographic projection of the first portion on the reference plane, and the reference plane is a plane in which a touch surface of the touch panel is disposed,
wherein the touch flexible printed circuit board comprises a first insulating layer, a first circuit layer, and a second insulating layer that are stacked in sequence along a direction distal from the touch panel;
wherein the first insulating layer comprises a first insulating portion and a second insulating portion; the first circuit layer comprises a first circuit portion, a second circuit portion, and a third circuit portion; and the second insulating layer comprises a third insulating portion, a fourth insulating portion, and a fifth insulating portion; and
the first portion comprises the first circuit portion and the third insulating portion; the second portion comprises the second insulating portion, the third circuit portion, and the fifth insulating portion; the bending portion comprises the first insulating portion, the second circuit portion, and the fourth insulating portion; the first insulating portion is made of a thermosetting ink, the thermosetting ink being a heat-set ink; and the first circuit unit comprises the first connection terminal.
