Title: Liquid crystal element
Inventor: SHINJO KATSUHIKO
IPC: G02F1/1337
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation and to enhance a contrast by setting the C director phase angle of liquid crystal molecules near the one boundary of liquid crystals larger than the C director phase angle of the liquid crystal molecules near the center in the thickness direction of a cell. SOLUTION: The C director phase angle (boundary phase angle) of the liquid crystal molecules near at least the one boundary of the liquid crystals is set larger than the C director phase angle (bulk phase angle) of the liquid crystal molecules near the center in the thickness direction. In such a case, the difference between the boundary phase angle and the bulk phase angle is set at >=5 deg. or both of the boundary phase angle and the bulk phase angle is set at >=10 deg. or the dielectric constant anisotropy (Δε) of the chiral smetic liquid crystals is set positive. The boundary phase angle on the side subjected to an orientation treatment is preferably larger than the bulk phase angle.  Further, the spectral characteristics are better if the phase angles in the cells are uniform and, therefore, the asymmetrical constitution subjected to the one side orientation treatment is better than the constitution subjected to both side orientation treatment.
