1. A liquid crystal display panel, comprising:
a first base;
a second base disposed opposite to the first base;
a liquid crystal layer disposed between the first base and the second base;
a first optical compensation layer disposed between the first base and the second base, an orthogonal projection of an optic axis of the first optical compensation layer on the first base being parallel to orthogonal projections of optic axes of liquid crystal molecules in the liquid crystal layer on the first base; and
a second optical compensation layer disposed on a side of the first base away from the liquid crystal layer, or disposed on a side of the second base away from the liquid crystal layer, an orthogonal projection of an optic axis of the second optical compensation layer on the first base being perpendicular to the orthogonal projection of the optic axis of the first optical compensation layer on the first base, wherein
a material of the first optical compensation layer and a material of the second optical compensation layer are both a material with positive dispersion; or
a material of the first optical compensation layer is a material with positive dispersion, and a material of the second optical compensation layer is a material with negative dispersion; or
a material of the first optical compensation layer is a material with negative dispersion, and a material of the second optical compensation layer is a material with positive dispersion; wherein
a sum of an in-plane retardation of the first optical compensation layer and an in-plane retardation of the liquid crystal layer is equal to a positive integral multiple of a first wavelength, the first wavelength being in a range of 535 nm±50 nm;
the in-plane retardation of the first optical compensation layer is in a range of 190 nm to 240 nm; and the in-plane retardation of the liquid crystal layer is in a range of 310 nm to 390 nm;
an in-plane retardation of the second optical compensation layer is in a range of 134 nm to 200 nm+550 nm×N, N being an integer greater than or equal to 0.
