Viewing angle characteristics of a negative type nematic liquid crystal (NLC) using a in-plain driven (IPD) VA cell mode without a negative compensation film on a homeotropic alignment layer were studied. Good voltage-transmittance curves were obtained using the rubbingaligned IPD-VA cell. However, instability and low transmittances of V-T characteristics in photo-aligned IPD-VA cell was measured. The viewing angle of a rubbingaligned IPD-VA cell without a negative compensation film was wider than that of photo-aligned IPD-VA cell and conventional VA cell Fabrication processes using a rubbing-aligned IPD-VA cell mode be carried out with only one-sided rubbing.
