Ultraviolet embossed alignment layers having patterned spacers for flexible liquid crystal display

Ultraviolet (UV) embossed alignment layers having patterned spacers for the flexible liquid crystal display (LCD) were designed and fabricated to prevent the problems caused by residual monomers in photopolymerization-assisted manufacturing of liquid crystal (LC) devices. UV embossed alignment layers with patterned spacers provided mechanical stability and better alignment properties of LC molecules in a bent environment, compared with LC device with the phase-separated polymer walls. In the patterned spacers of UV embossed LC cell, the column-shaped spacer which has isotropic configuration of spacers provided good LC alignment during bending process.
