Abstract:
A color liquid crystal display, comprising:a liquid crystal device holding a twist-aligned nematic liquid crystal between a pair of substrates made up of a first substrate having a first electrode and a second substrate having a second electrode;a pair of polarizing films disposed holding said liquid crystal device thereinbetween; anda twisted retardation film disposed between said liquid crystal device and one of said pair of polarizing films, whereinan intersecting angle of absorption axes of said pair of polarizing films is arranged to be in a range of 60 degrees to 120 degrees;a .DELTA.nd value of said liquid crystal device expressed by a product of a difference .DELTA.n of birefringence of said nematic liquid crystal and a space d between said pair of substrates is arranged to be in a range of 1500 nm to 1800 nm; anda .DELTA.nd value of said twisted retardation film expressed by a product of a difference .DELTA.n of birefringence of said twisted retardation film and a thickness d of said twisted retardation film is arranged in a range similar to the .DELTA.nd value of said liquid crystal device, so that a black display results when no voltage is applied.
