摘要： The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy, comprising a low-molecular-weight component and a polymerizable component. The polymerizable component comprises self-aligning, polymerizable mesogens (polymerizable self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the LC medium without alignment layers. The invention discloses novel structures for polymerizable self-alignment additives which have a certain position of the functional groups.

摘要： Mesogenic compounds of formula I-Z are suitable for use in mesogenic media. Such mesogenic media can exhibit a blue phase and comprise component A, consisting of one or more compounds of formula I-Z, and, optionally a component B, consisting of one or more compounds selected from the group of compounds of formulae I-M and I-U, wherein the parameters are as defined herein. The media can also be stabilized by a polymer. The media can be used in electro-optical light modulation elements and displays.
