Display panel and display terminal

The invention discloses a display panel and a display terminal. The display panel comprises a substrate and a pixel definition layer, wherein the pixel definition layer comprises a first retaining wall and a second retaining wall which are spaced; the thickness of the second retaining wall is larger than that of the first retaining wall, the second retaining wall at least comprises a first sub-part and a second sub-part which are stacked, the orthographic projection of the second sub-part on the first sub-part is located in the first sub-part, and the thickness of the central area of the second sub-part is larger than that of the edge area of the second sub-part. The taper angle of the second sub-part is smaller than or equal to that of the first sub-part. The thickness of the second retaining wall is set to be larger than that of the first retaining wall, so that the second retaining wall can replace the supporting column to support the photomask in the technological process. The taper angle of the second su
