Abrégé

The present application discloses a display panel and a display apparatus. The display panel comprises: a substrate; a shading layer, the shading layer comprising a first shading unit, a second shading unit, and a third shading unit. The contour of each of the orthographic projection of the first shading unit, the orthographic projection of the second shading unit, and the orthographic projection of the third shading unit onto the substrate is a pattern having a curved edge; the contour sizes of the orthographic projection of the first shading unit, the orthographic projection of the second shading unit, and the orthographic projection of the third shading unit onto the substrate decrease sequentially; a difference value between the contour size of the orthographic projection of the second shading unit onto the substrate and the average of the contour sizes of the orthographic projections of the first shading unit and the third shading unit on the substrate is smaller than or equal to a preset numerical value.
