Abstract:
A scattering fringe field optical-compensated reflective liquid crystal display comprising:a TFT plate; a color filter plate; a liquid crystal layer of a negative dielectric anisotropy sandwiched between said TFT plate and color filter plate, said liquid crystal layer having an ordinary and extraordinary refractive index n0 and ne, a cell gap g and a rubbing direction; a reflective electrode structure on said TFT plate for applying a fringe field to said liquid crystal layer, said reflective electrode structure including a common electrode and a pixel electrode with an insulator therebetween, said common electrode consisting of a plurality of strips; a scattering film between said liquid crystal layer and color filter plate; a compensator on said color filter plate, said compensator having a thickness t, an extension axis and respective refractive index nx, ny and nz in three axes; and a polarizer with a polarization direction arranged outside said color filter plate, said polarization direction having an angle &phgr;R from said extension axis and an angle &phgr;LC from said rubbing direction; wherein &thgr;LC=(neâˆ’no)Ã—g and R=(nxâˆ’(ny+nz)/2)Ã—t, and said liquid crystal layer, compensator and polarizer are arranged under a condition of |&thgr;LCâˆ’2R|&lE;30 nm and 85Â°&lE;|&phgr;Râˆ’&phgr;LC |&lE;95Â°, or |2&thgr;LCâˆ’R|&lE;30 nm, 40Â°&lE;(&phgr;LCâˆ’2&phgr;R)&lE;50Â° and |&phgr;Râˆ’14Â°|&lE;8Â°.
