ABSTRACT:
A bend-aligned liquid crystal cell is manufactured by irradiating first and second alignment layers with first and second polarized ultraviolet lights to impart first and second pretilt angles in the first and second alignment layers, and injecting molecules of liquid crystal material between the first and second alignment layers. The alignment layers include polysiloxane based materials or polyvinylfluorocinnamate in which the pretilt angle of the alignment layer is changeable according to the ultraviolet absorption energy.
