Patent ID: 7570335

Claim:
An in-plane switching liquid crystal display device, comprising: a first substrate; a second substrate spaced apart from the first substrate; a liquid crystal layer between the first and second substrates; a first polarizer at an outer surface of the first substrate, the first polarizer including a first polarization film and first inner and outer supporting films at opposite sides of the first polarization film, the first inner supporting film adjacent to the first substrate and having a retardation value within a range of about −10 nm to about +10 nm; and a second polarizer at an outer surface of the second substrate, the second polarizer including a second polarization film and second inner and outer supporting films, at opposite sides of the second polarization film, the second inner supporting film adjacent to the second substrate, wherein a color shift from viewing the in-plane switching liquid crystal display device is minimized to a range of about 0.2-0.3 for “x” coordinate and 0.2-0.3 for “y” coordinate in the International Commission on Illumination (CIE) chromaticity diagram.
