Abstract: A compensation system for liquid crystal panels and a liquid crystal display are disclosed. The compensation system includes a first biaxial compensation film and a second biaxial compensation film respectively arranged on two sides of the liquid crystal panel. When the wavelength of incident lights is 550 nm, an in-plain retardation value of the first biaxial compensation film is Ro1, a thickness retardation value of the first biaxial compensation film is Rth1, an in-plain retardation value of the second biaxial compensation film is Ro2, and a thickness retardation value of the second biaxial compensation film is Rth2. Wherein 35 nmRo187.5 nm; 80 nmRth1200 nm; 28 nmRo289.6 nm; Y1Rth2Y2; Y1=0.005389×Rth12−2,367048×Rth1+323. 45; Y2=−0.003571×Rth12+0.085714×Rth1+226.74. By configuring the retardation values of the double-layers biaxial compensation films, the dark-state light leakage of the liquid crystal panels may be reduced.
