IMPROVING THE STABILITY OF ION BEAM GENERATED ALIGNMENT LAYERS BY SURFACE MODIFICATION

A method for preparing a alignment layer surface provides a surface on the alignment layer. A chemically modified surfae [117] is formed as a result of quenching and/or ion beam treatment in accordance with the present invention, and reactive gas is introduced to the ion beam to saturate dangling bo...

Zusammenfassung:	A method for preparing a alignment layer surface provides a surface on the alignment layer. A chemically modified surfae [117] is formed as a result of quenching and/or ion beam treatment in accordance with the present invention, and reactive gas is introduced to the ion beam to saturate dangling bonds on the surface. Layer [117] is now substantially free from dangling bonds and free radicals which could degrade properties of a liquid crystal display. Now, a substrate [101] is formed for use in a liquid crystal displax device. Another method for preparing an alignment layer. The surface is bombarded with ions and quenched with a reactive component to saturate dangling bonds on the surface. ® KIPO & WIPO 2007
