1. A liquid crystal display panel comprising:
a backlight module;
a first polarizer disposed on a side of the backlight module; and
an array substrate disposed on a surface on a side of the first polarizer away from the backlight module;
wherein the first polarizer comprises:
a polarizing film disposed between the array substrate and the backlight module; and
a plurality of microlens structures arranged in an array on a side of the polarizing film facing the backlight module;
wherein the backlight module comprises a first prism film, and a surface on a side of the first prism film adjacent to the array substrate has a plurality of triangular prism structures arranged in an array and protruding toward the array substrate;
a first groove is defined between two adjacent ones of the plurality of triangular prism structures, and each of the plurality of microlens structures covers at least one of the plurality of first grooves;
any two adjacent ones of the plurality of microlens structures are abutted against each other, and an abutting side of any two adjacent ones of the plurality of microlens structures is disposed corresponding to a ridge on a side of one of the plurality of triangular prism structures adjacent to the polarizing film.
