    Abstract: A touch display panel, a fabrication method thereof, and a touch display apparatus are provided. The touch display panel comprises an array substrate (20) and an opposite substrate which are arranged to face each other, the opposite substrate includes a plurality of touch sensing electrodes distributed in a row direction. The array substrate (20) includes a plurality of touch driving electrodes (201) distributed in a column direction, a plurality of touch driving electrode wires (202) distributed in the row direction, and a plurality of touch driving electrode connection wires (203) which are distributed in the column direction and are insulated from the touch driving electrode wires (202). Each column of touch driving electrodes (201) include a plurality of touch driving electrode blocks (2011), each of the touch driving electrode blocks (2011) is connected with one touch driving electrode wire (202), and different columns of touch driving electrode blocks (2011) are connected with different touch driving electrode wires (202). Each of the touch driving electrode blocks (2011) includes a plurality of interruptedly distributed touch driving electrode units (2012), and the touch driving electrode units (2012) of each of the touch driving electrode blocks (2011) are electrically connected by the touch driving electrode connection wires (203). An orthogonal projection of the touch driving electrode wire (202) connected with corresponding touch driving electrode block (2011) on the array substrate does not overlap with orthogonal projections of the touch driving electrode units (2012) of other touch driving electrode blocks (2011) than the corresponding touch driving electrode block (2011) on the array substrate. Crosstalk of the touch display panel is reduced, and a touch effect of the touch display panel is improved.
