1. An organic light-emitting diode (OLED) display panel comprising:
a main display part having a display area and a non-display area disposed around the display area, and comprising a driving substrate and a first electrode arranged in sequence;
a first inorganic packaging layer disposed on the first electrode and extending from the display area to the non-display area;
a first organic packaging layer disposed on the first inorganic packaging layer, wherein the first organic packaging layer comprises a first organic packaging section and a second organic packaging section, the first organic packaging section is located in the non-display area, the first organic packaging section comprises water absorbent, and the second organic packaging section covers the first electrode and is connected with a surface of the first organic packaging section close to the display area;
a second inorganic packaging layer disposed between the first inorganic packaging layer and the first organic packaging layer, and extending from the display area to the non-display area;
a second organic packaging layer disposed between the first inorganic packaging layer and the second inorganic packaging layer, and extending from the display area to the non-display area;
a third inorganic packaging layer disposed on the first organic packaging layer, and extending from the display area to the non-display area;
a first retaining wall disposed on the driving substrate and located at a side of the first organic packaging section away from the display area; and
a second retaining wall disposed on the driving substrate and located at a side of the first retaining wall close to the display area;
wherein the first organic packaging section comprises a vertical portion and a horizontal portion connected to the vertical portion; the vertical portion is disposed at a side of the second retaining wall away from the first retaining wall, and a side surface of the vertical portion close to the display area is in contact with a side surface of the second organic packaging section and a side surface of the second inorganic packaging layer; and the horizontal portion and the second inorganic packaging layer both cover an upper surface of the second retaining wall, and the horizontal portion is in contact with an upper surface of a part of the second inorganic packaging layer located above the second retaining wall.
