1. A display panel, comprising:
a substrate;
a light-emitting device layer located at a side of the substrate, wherein the light-emitting device layer comprises pixel apertures arranged in an array and light-emitting devices one-to-one corresponding to the pixel apertures, and-one of the light-emitting devices is located in a respective one pixel aperture of the pixel apertures; and
a color resist layer located at a side of the light-emitting device layer facing away from the substrate, wherein the color resist layer comprises color resist units arranged in an array, one of the color resist units comprises a first portion and a second portion, a projection of the second portion on the substrate is located outside a projection of the first portion on the substrate, and a projection of the first portion on the light-emitting device layer is located in a respective one pixel aperture of the pixel apertures,
wherein a thickness of the first portion of at least one of the color resist units in a first direction is larger than or equal to a thickness of the second portion of the at least one of the color resist units in the first direction, where the first direction is a direction in which light exits from the display panel,
wherein the projection of the auxiliary layer on the substrate completely covers a projection of the color resist layer on the substrate, and
wherein fourth grooves are formed at a surface of the auxiliary layer facing away from the substrate; and a projection of the light-shielding layer on the auxiliary layer covers the fourth grooves.
