Abstract
The present invention relates to a polymer containing scattering type VA liquid crystal device with very low hysteresis characteristics. The reduction of the hysteresis is achieved by providing a pretilt angle.
Claims17
A method for manufacturing a polymer containing scattering type liquid crystal device, comprising the steps:
- providing two substrates with electrodes manufacturing a cell by arranging the two substrates with the electrodes on the inner side facing each other with a gap between the substrates, filling the cell with a liquid crystal mixture comprising a liquid crystal material having negative dielectric anisotropy and a polymer precursor, applying alignment treatment for the liquid crystal mixture either before or after filling the cell with the liquid crystal mixture, such that the liquid crystal mixture is oriented with a pretilt angle inclined from the normal direction to the substrate, and polymerizing the polymer precursor at a temperature higher than the clearing temperature of the liquid crystal mixture.
