Functional films using reactive mesogens for display applications

Functional films made of reactive mesogens (RMs) are widely used in display devices such as liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs). While functional RM films have been intensively developed for commercial application in the industrial sector, the fundamental studies on it in the academic sector are relatively limited. Here, functional RM films are reviewed in terms of their materials and fabrication processes as well as their applications in display devices. Also briefly reviewed is the recent research on them that may potentially be used in future display devices. This review was intended to provide an overall summary of RM applications in display devices and of the recent trends of the relevant studies to non-experts as well as experts in display applications.
