Recently, high-birefringence (Δn) liquid crystalline (LC) materials have been increasingly used in various optical devices such as organic light-emitting diodes (OLEDs), 1 photostorage devices, 2 laser-emitting films, 3 and telecommunication devices, 4 and such materials are being extensively investigated from the viewpoint of finding even more applications. These materials have a small cell gap and small film thickness, leading to a short response time that ...
