Touch display panel and touch display apparatus

A touch display apparatus comprising a touch display panel, wherein the touch display panel comprises:

• a substrate comprising a display area and non-display areas;
• an organic light emitting device formed in the display area of the substrate;
• at least one retaining wall arranged in the non-display areas of the substrate, wherein the at least one retaining wall comprises a first retaining wall which is adjacent to the display area, and a width of the at least one retaining wall is greater than or equal to 30 μm and less than or equal to 200 μm;
• a thin film encapsulation layer, wherein the thin film encapsulation layer is arranged on the organic light emitting device, and the thin film encapsulation layer comprises at least one inorganic encapsulation layer and at least one organic encapsulation layer, and the thin film encapsulation layer covers the at least one retaining wall, a height difference between the first retaining wall and a part of the thin film encapsulation layer located between the first retaining wall and the display area is greater than or equal to 0 μm and less than or equal to 3 μm;
• touch electrodes, wherein the touch electrodes are arranged on the thin film encapsulation layer, and at least a part of at least one of the touch electrodes is located in the display area of the substrate;
• and
• electrode wires, wherein at least a part of at least one of the electrode wires is located in the non-display area of the substrate, is disposed on the thin film encapsulation layer, and is arranged along an extension direction of the at least one retaining wall, wherein projections of the electrode wires on the substrate are located within a projection of the at least one retaining wall on the substrate.
