1. A touch display panel, comprising:
a base substrate, comprising: a display region and a peripheral region surrounding the display region;
a display function layer, located on a side of the base substrate and comprising: at least one organic insulation layer and an encapsulation layer located on a side of the organic insulation layer facing away from the base substrate, wherein an orthographic projection of the encapsulation layer on the base substrate covers the display region and part of the peripheral region; and
a touch function layer, located on a side of the encapsulation layer facing away from the base substrate and comprising: a touch conductive layer and an inorganic insulation layer making contact with the touch conductive layer, wherein the touch function layer comprises: a first touch conductive layer, and a second touch conductive layer located on a side of the first touch conductive layer facing away from the display function layer, the inorganic insulation layer comprises at least: a first inorganic insulation layer located between the first touch conductive layer and the second touch conductive layer;
wherein the peripheral region comprises: at least one fan-out region, and the fan-out region comprises: a bending region;
the touch function layer comprises at least one inorganic insulation layer removal region; and
an orthographic projection of the inorganic insulation layer removal region on the base substrate covers the bending region;
wherein the organic insulation layer has at least one groove penetrating through a thickness of the organic insulation layer, and the groove is at least located between the bending region and the display region; and
between the bending region and the display region, the orthographic projection of the inorganic insulation layer removal region on the base substrate covers the groove.
