Patent ID: 8199291

Claim:
A liquid crystal display device comprising in the following order: a light source, a first polarizer, a first transparent film, a liquid crystal cell comprising: a pair of transparent substrates and a polymer-stabilized blue phase liquid crystal layer disposed therebetween; a second transparent film, and a second polarizer; wherein |Re(550)|, which is an absolute value of retardation in plane at 550 nm, Re(550), of the first transparent film is equal to or smaller than 10 nm; and |Rth (550)|, which is an absolute value of retardation along the thickness direction at 550 nm, Rth(550), of the first transparent film is equal to or smaller than 30 nm; and wherein the second transparent film comprises a biaxial film whose Re(550) is from 20 to 120 nm and Rth(550) is from 125 to 225 nm, and another biaxial film, or the second transparent film comprises a uniaxial film whose Re(550) is from 60 to 210 nm and Rth(550) is from 30 to 105 nm, and another uniaxial film.
