1. A display panel, comprising a plurality of opening areas, the display panel comprising:
an array substrate;
a color filter substrate disposed opposite to the array substrate and comprising a plurality of color resist portions located in the opening areas;
a backlight module disposed on one side of the array substrate farthest from the color filter substrate; and
an optical layer disposed in at least one of the color filter substrate and the array substrate and arranged corresponding to at least the plurality of color resist portions, wherein the optical layer is configured to converge light;
wherein the optical layer comprises:
an optical structure layer, comprising a plurality of protrusions; and
an optical protective layer, at least disposed on a first side of the optical structure layer, wherein the first side is a side where the plurality of protrusions protrude;
wherein a refractive index of the plurality of protrusions is greater than a refractive index of the optical protective layer;
wherein the plurality of protrusions comprise a plurality of first protrusions, the plurality of first protrusions are column-shaped, a top of each of the plurality of first protrusions is parallel to a bottom of the first protrusion, and at least one side of each of the plurality of first protrusions is parallel to and located adjacent to either the array substrate or the color filter substrate;
wherein in a length direction, an orthographic projection of each of the plurality of first protrusions projected on the color filter substrate covers n of the plurality of color resist portions of a same color, n is a positive integer; an orthographic projection of the top of each first protrusion projected on the color filter substrate is positioned between two corresponding ones of the plurality of color resist portions; and an orthographic projection of the bottom of each first protrusion is positioned between two corresponding ones of the plurality of color resist portions.
