Display panel comprising an encapsulation layer, display device, and manufacturing methods thereof

A display device, comprising:

• a display panel, comprising:
• a flexible substrate having a display area and a non-display area;
• a dam structure, located in the non-display area and disposed around the display area;
• a plurality of grooves disposed on the non-display area between the display area and the dam structure, wherein each groove of the plurality of grooves is spaced apart from each adjacent groove of the plurality of grooves, and the plurality of grooves includes one or more first grooves;
• and
• an organic encapsulation layer covering the display area, at least a portion of the non-display area, and the plurality of grooves;
• a transparent cover;
• wherein
• the transparent cover is in face-sharing contact with the display panel;
• and
• a flat layer disposed on the flexible substrate, the flat layer covering at least the display area, wherein the one or more first grooves are located between the display area and an edge of the flat layer.

A method of manufacturing a display panel, the method comprising:

• forming a flexible substrate on a rigid substrate, the flexible substrate having a display area and a non-display area;
• forming a dam structure in the non-display area and around the display area;
• forming one or more grooves on the non-display area between the display area and the dam structure;
• forming an organic encapsulation layer on the flexible substrate;
• peeling off the rigid substrate;
• wherein
• the organic encapsulation layer covers the display area, at least a portion of the non-display area, and the one or more grooves;
• forming a flat layer on the flexible substrate;
• and
• forming a display structure layer on the display area on a side of the flat layer away from the flexible substrate;
• wherein
• the flat layer covers at least the display area;
• the one or more grooves comprise one or more first grooves, and the one or more first grooves are located between the display area and an edge of the flat layer.
