Abstract
A liquid crystal display panel includes a first polarizer, a second polarizer, a liquid crystal layer including first liquid crystal molecules, a first optical compensation layer between the liquid crystal layer and any of the first polarizer and the second polarizer, a second optical compensation layer on a same side of the liquid crystal layer as the first optical compensation layer. In a non-powered state of the liquid crystal display panel orthographic projections of optical axes of the first liquid crystal molecules on the first polarizer, which are perpendicular to an orthographic projection of an optical axis of the first optical compensation layer on the first polarizer, are parallel to any of transmission axes of the first polarizer and the second polarizer that are perpendicular to each other. An optical axis of the second optical compensation layer is perpendicular to a plane where the second optical compensation layer is located.
