Abstract:
A polymerizable liquid crystal composition is provided that can contains a mixture of polymerizable compounds containing a compound represented by the formula (1-1), a compound represented by the formula (2), a compound represented by the formula (3-1) and a compound represented by the formula (4), and a amine silane coupling agent. The composition can form a polymerizable liquid crystal layer exhibiting a uniform homeotropic alignment by coating the composition on a supporting substrate, independently from the kind of the supporting substrate without a special alignment film. Examples of each of the components are shown below, in which ring T represents triptycen-1,4-diyl.
