The disclosure relates to a touch display panel, including a first substrate, an organic light emitting diode (OLED) device layer, a spacer, a first touch electrode, a second touch electrode, and a second substrate opposite to the first substrate. The OLED device layer is disposed on the first substrate and has a light emitting area. The spacer is disposed on the OLED device layer and located outside the light emitting area. The first touch electrode and the second touch electrode are disposed on the OLED device layer. The first touch electrode has a first bridge part. The first bridge part of the first touch electrode is interlaced with the second touch electrode. In particular, at least a portion of the first bridge part is disposed on the spacer.
