1. A liquid crystal display panel, comprising a plurality of sub-pixels defined by a light shielding matrix and arranged in an array, an array substrate, and an opposing substrate spaced apart from the array substrate, wherein:
the opposing substrate comprises a first substrate and a plurality of spacers, the plurality of spacers being on a side of the first substrate close to the array substrate and being within a light shielding area of the light shielding matrix;
the array substrate comprises a second substrate and a plurality of protrusion structures, the plurality of protrusion structures being on a side of the second substrate close to the opposing substrate, and being within the light shielding area of the light shielding matrix;
wherein the plurality of protrusion structures comprise a first protrusion structure and a second protrusion structure, an orthographic projection of the first protrusion structure on the second substrate and an orthographic projection of the second protrusion structure on the second substrate being between an orthographic projection of one of the plurality of spacers on the second substrate and a sub-pixel adjacent to the one of the plurality of spacers, and a minimum distance between the orthographic projection of the first protrusion structure on the second substrate and the orthographic projection of the one of the plurality of spacers on the second substrate being less than a minimum distance between the orthographic projection of the second protrusion structure on the second substrate and the orthographic projection of the one of the plurality of spacers on the second substrate; and
at least one of the first protrusion structure or the second protrusion structure comprises at least two sub-protrusions arranged to be spaced apart from each other along a second direction, wherein the second direction is parallel to the second substrate and orthogonal to the first direction.
