摘要: The alignment layers and spacers between two polymeric substrates are indispensable components for flexible liquid crystal displays (LCDs). Photoalignment with were prepared by a contact-free method using UV patternable UV-curable materials on polyethersulfone (PES) films. Well-aligned the direction of photoalignment layer was observed polarized microscope. Spacers played significant role in preventing disruption ordering crystal. substrate without any physical contact free from problems that found rubbing or micro stamp replication method. Additionally this can be used wide areas manufacturing large sized displays.
