ABSTRACT:
A liquid crystal display device is characterized by comprising first and second substrates on a surface of which electrodes are formed, a liquid crystal material with ferroelectricity or antiferroelectricity interposed between the first and second electrodes, and an orientation film and disposed between the electrode or electrodes formed on the surface of said first and/or second substrate whose surface has been subjected to a process which gives optically uniaxial orientation to the liquid crystal material, wherein said orientation film has a pretilt angle of 1.6 to 3.1 degree with respect to a nematic liquid crystal. Further, a value of a polar term of surface tension on the surface of the orientation film ranges from 11 to 15 dyne/cm.
