Display panel, display device, and method of manufacturing display panel

A method of manufacturing a display panel, comprising:

• obtaining a to-be-processed panel, the to-be-processed panel comprising a driving structure layer and a plurality of overhang structures arranged on a surface of a side of the driving structure layer and spaced apart from each other, each of the plurality of overhang structures comprising a first precursor and a second precursor sequentially stacked on one another, the first precursor being arranged between the second precursor and the driving structure layer, both sides of a bottom of the second precursor extending beyond a top surface of the first precursor, and the driving structure layer having a display region and a border region located around the display region;
• removing at least a part of the second precursor on a side away from the display region that extends beyond the first precursor to obtain a second barrier portion and obtain a dam structure comprising the first precursor and the second barrier portion;
• wherein an angle between an outer side surface of the second barrier portion away from the display region and a bottom surface of the second barrier portion is an acute angle;
• and
• forming an encapsulation structure layer on a side of the driving structure layer where the dam structure is arranged.

A display device, comprising:

• a display panel having a display region and a border region located around the display region, the display panel comprising:
• a driving structure layer;
• an encapsulation structure layer, wherein the driving structure layer and the encapsulation structure layer are sequentially stacked on one another;
• and
• a dam structure, arranged in the border region, located between the encapsulation structure layer and the driving structure layer, and comprising:
• a first barrier portion;
• and
• a second barrier portion, wherein the first barrier portion and the second barrier portion are sequentially stacked in a direction from the driving structure layer to the encapsulation structure layer, an orthographic projection of an edge of a bottom surface of the second barrier portion away from the display region projected onto a top surface of the first barrier portion is located within the top surface of the first barrier portion, and an angle between an outer side surface of the second barrier portion away from the display region and the bottom surface of the second barrier portion is an acute angle or a right angle;
• and
• a power supply, connected to the display panel and configured to supply power to the display panel.
