1. An organic light-emitting diode (OLED) panel, comprising:
a pixel array comprising a plurality of light-emitting elements; wherein
each of the plurality of light-emitting elements comprises a fence structure, a first electrode layer, a pixel definition layer, a first charge transport layer, a light-emitting layer, a second charge transport layer, and a second electrode layer, that which are stacked on a substrate in sequence; and
the pixel definition layer comprises an opening that exposes part of the first electrode layer; a vertical projection of the fence structure on the substrate is located inside a vertical projection of the opening on the substrate; a trench is formed between a sidewall of the fence structure and a sidewall of the opening, and the first charge transport layer comprises a discontinued portion in the trench;
wherein a vertical projection of the fence structure on the substrate exhibits a substantially ring shape, and the fence structure comprises at least one notch which has a depth larger than 25% of the height of the fence structure.
