1. A liquid crystal display panel, comprising:
a first polarizer;
a second polarizer disposed opposite to the first polarizer, a transmission axis of the first polarizer being perpendicular to a transmission axis of the second polarizer;
a first liquid crystal layer disposed between the first polarizer and the second polarizer, wherein the first liquid crystal layer includes first liquid crystal molecules, and an included angle between an orthogonal projection of an optical axis of a first liquid crystal molecule on the first polarizer and the transmission axis of the first polarizer is an acute angle; and
an optical compensation layer disposed between the first liquid crystal layer and one of the first polarizer and the second polarizer; wherein an orthogonal projection of an optical axis of the optical compensation layer on the first polarizer is perpendicular to the orthogonal projection of the optical axis of the first liquid crystal molecule on the first polarizer; and
an absolute value of a difference between an in-plane retardation of the optical compensation layer and an in-plane retardation of the first liquid crystal layer is less than or equal to 30 nm.
