Claim 17:
18. A method of manufacturing a liquid crystal display panel, comprising:
providing a first base and a second base;
forming a liquid crystal layer between the first base and the second base;
forming a first optical compensation layer 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
forming a second optical compensation layer on a side of the first base away from the liquid crystal layer or 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 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 185 nm±5 nm; and the in-plane retardation of the liquid crystal layer is in a range of 350 nm±5 nm; and
an in-plane retardation of the second optical compensation layer is in a range of (147 nm±10 nm)+550 nm×N, N being an integer greater than or equal to 0.
