Reverse-tilt-domain boundary wall in a polymer-encapsulated flexible liquid crystal display

A reverse-tilt-domain boundary wall in a polymer-encapsulated nematic liquid crystal was examined. A boundary wall in which the liquid crystal director was nearly planar midway through the wall was formed during UV polymerization; it remained stable even though the liquid crystal molecules in neighboring domains are nearly vertically aligned. The formation of the boundary wall was found to be suppressed by the oblique irradiation with linearly polarized UV light.
