| titleOfInvention | Liquid crystal optical element, a method for producing the same and a projection type liquid crystal display apparatus |
| abstract | To a bifunctional acrylurethane compound having acrylate groups at its both ends, which is a reaction product of polypropylene glycol, a mixture of 2,2,4-trimethyl-1, 6-diisocyanatohexane and 2,4,4-trimethyl-1,6-diisocyanatohexane, and 2-hydroxyethyl acrylate, 2-ethylhexyl acrylate, 2-hydroxyethyl acrylate, nematic liquid crystal and a photo-reaction initiator are mixed to obtain a uniformly dissolved mixture, and the mixture undergoes a phase separation treatment by photo-polymerization to thereby form a liquid crystal/polymer composite material layer 7 which is utilized for a liquid crystal optical element 1. The phase separation by photo-polymerization improves controllability of the structure of the liquid crystal/polymer composite material layer. In particular, the shape of the polymer phase with respect to the liquid crystal phase is precisely controlled to adjust the optical characteristic performance of liquid crystal domains in a connected phase of liquid crystal; to improve the electro-optical characteristics in a low temperature region, and to obtain a display of high contrast and low hysteresis. |
