1. A touch display panel, comprising:
a base substrate;
a display device layer, arranged on a side of the base substrate;
a touch function layer, arranged on a side of the display device layer away from the base substrate, wherein
the touch function layer comprises an inorganic dielectric layer and an organic protection layer sequentially stacked on the display device layer; and
an orthographic projection of at least part of an edge of the inorganic dielectric layer on the base substrate is located within an orthographic projection of the organic protection layer on the base substrate, wherein
the display device layer comprises an organic material layer;
a peripheral area of the touch display panel comprises a first area;
in the first area, an edge of the organic material layer is located within the edge of the inorganic dielectric layer;
the peripheral area of the touch display panel further comprises a bendable area; and
the organic material layer covers the bendable area, and the inorganic dielectric layer and the organic protection layer are hollowed out in the bendable area, wherein
an edge of the organic protection layer close to the bendable area is located between the bendable area and an edge of the inorganic dielectric layer close to the bendable area.
