Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A liquid crystal display panel comprising:
a first polarizer;
a second polarizer disposed opposite to the first polarizer;
a liquid crystal layer disposed between the first polarizer and the second polarizer, the liquid crystal layer comprising liquid crystal molecules whose optical axes are all parallel to an initial direction in the case where the liquid crystal display panel is not powered on;
a first optical compensation film disposed between the first polarizer and the second polarizer; wherein an optical axis of the first optical compensation film is parallel to a plane where the first optical compensation film is in; and
a second optical compensation film disposed between the first polarizer and the second polarizer, wherein an optical axis of the second optical compensation film is parallel to a plane where the second optical compensation film is in;
wherein in-plane retardation RO2 of the second optical compensation film is equal to in-plane retardation RO1 of the first optical compensation film; and
the optical axis of the first optical compensation film is perpendicular to the optical axis of the second optical compensation film.
