Display panel, display apparatus, and method for manufacturing display panel

A display apparatus, comprising a display panel, comprising:

• a substrate;
• a first power signal line provided on the substrate;
• a conductive layer provided over the first power signal line and connected with the first power signal line, the conductive layer comprising a plurality of conductive portions;
• a pixel defining layer comprising pixel defining portions, first openings and second openings that are formed in the pixel defining portions, orthographic projections of the second openings on the substrate and orthographic projections of the plurality of conductive portions on the substrate at least partially overlapping;
• a light emitting layer provided on a side of the substrate where the conductive layer is located, the light emitting layer comprising a plurality of light emitting portions disposed corresponding to the first openings;
• dam portions provided on the substrate and surrounding the plurality of conductive portions, a material of the dam portions having no affinity with a material of the light emitting portions;
• first electrodes provided on a side of the light emitting layer and the dam portions away from the substrate and connected with the conductive portions via the second openings.

A method for manufacturing a display panel, comprising:

• providing a conductive material layer on a substrate, and patterning the conductive material layer to form a first power signal line;
• further providing a conductive material layer on the substrate with the first power signal line, and patterning the conductive material layer to form a conductive layer comprising a plurality of conductive portions located on a side of the first power signal line away from the substrate;
• providing a pixel defining material layer on the substrate, and patterning the pixel defining material layer to form first openings and second openings, at least part of the conductive portions being exposed via the second openings;
• providing a hydrophobic material layer on the substrate, and patterning the hydrophobic material layer to obtain dam portions provided surrounding the conductive portions;
• further manufacturing a light emitting layer comprising a plurality of light emitting portions on the substrate, the light emitting portions being at least partially located in the first openings;
• further manufacturing first electrodes on the substrate, the first electrodes being connected with the conductive portions via the second openings.
