Abstract: A liquid crystal display panel includes a first base, a second base disposed opposite to the first base, a liquid crystal layer and a first optical compensation layer that are disposed between the first base and the second base, and a second optical compensation layer disposed 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 first optical compensation layer on the first base is parallel to orthogonal projections of optic axes of liquid crystal molecules in the liquid crystal layer on the first base. An orthogonal projection of an optic axis of the second optical compensation layer on the first base is perpendicular to the orthogonal projection of the optic axis of the first optical compensation layer on the first base.
