LCD WITH A PAIR OF RETARDATION FILMS ON ONE SIDE OF LIQUID CRYSTAL LAYER |
摘要 |
A normally white twisted nematic liquid crystal display is disclosed having a pair of retardation films disposed between the liquid crystal layer and an adjacent polarizer, both retardation films being on one side of the liquid crystal layer. Both retardation films, if uniaxial, have retardation values of from about 100 - 200 nm. Optionally, biaxial retarders (nx > ny > nz) may be used, such biaxial retarders having retardation values from about .DELTA.zx = -100 to -200 nm, and .DELTA.zy = -10 to -100 nm. Accordingly, inversion is reduced and contrast rations are improved at large viewing angles.
