IN PLANE SWITCHING MODE LIQUID CRYSTAL DISPLAY DEVICE HAVING OPTICAL COMPENSATION FILM

An in-plane switching mode liquid crystal display device which reduces a color shift while preventing leakage in a diagonal direction is provided to improve image quality by improving color shift according to the viewing angle of in-plane switching LCD. A first polarizer(105) is positioned in a lowe...

Zusammenfassung:	An in-plane switching mode liquid crystal display device which reduces a color shift while preventing leakage in a diagonal direction is provided to improve image quality by improving color shift according to the viewing angle of in-plane switching LCD. A first polarizer(105) is positioned in a lower part of an LCD(Liquid Crystal Display) panel. The first polarizer includes a first supporter(102), a second supporter(104) and a first polarizing device positioned between the first supporter and the second supporter. A second polarizer is positioned on the top of the LCD panel. The second polarizer includes the third supporter, an optical compensation films and a second azimuth rotator positioned between the third supporter and first and second optically compensatory films. The first optically compensatory film is made of the negative biaxial film. The second optically compensatory film is made of the negative A plate.
