1. A touch display panel, including:
a display substrate, including:
a base substrate;
a signal line, located on the base substrate;
a first electrode layer, located on a side of the signal line away from the base substrate; and
a second electrode layer, located on a side of the first electrode layer away from the base substrate,
a first conductive layer, located on the display substrate;
a touch insulation layer, located on a side of the first conductive layer away from the display substrate; and
a second conductive layer, located on a side of the touch insulation layer away from the first conductive layer,
the first conductive layer includes a touch conductive structure, the second conductive layer includes a plurality of touch electrodes, the first electrode layer includes a plurality of first electrodes, and the second electrode layer includes a plurality of second electrodes;
the touch display panel further includes a shielding conductive pattern, an orthographic projection of the shielding conductive pattern on the base substrate overlaps with an orthographic projection of the signal line on the base substrate and an orthographic projection of at least one of the plurality of touch electrodes on the base substrate respectively,
the shielding conductive pattern is located in the first conductive layer and insulated from the touch conductive structure, or the shielding conductive pattern is located in the second electrode layer and insulated from the second electrode.
