DISPLAY DEVICE

摘要

A display device comprises a VA liquid crystal display unit as well as a front side polarizer and a rear side polarizer arranged respectively at both side of the VA liquid crystal display unit; wherein the VA liquid crystal display unit has an optical path difference Δnd of 324.3 nm to 305.8 nm at the wavelength of 550 nm; the front side polarizer is arranged at a side in the light-exiting direction of the VA liquid crystal unit; one of the front side polarizer and the rear side polarizer includes the biaxial compensation film, which has an in-plane delay Ro of 50.4-78 nm at the wavelength of 550 nm and a thickness direction delay Rth-b of 168-260 nm at the wavelength of 550 nm. The amount of light leakage is significantly reduced with the contrast close to the horizontal viewing angle obviously increased and the display effect further improved.
