Abstract The performance of ferroelectric liquid crysta displays are particularly sensitive to achieving the correct alignment conditions. Topographical studies of the surface layers of a colour FLCD have been made using tapping mode atomic force (AFM). The results are compared with detailed studies of test cells at different stages of device fabrication. An understanding of the relationship between the nanoscopic structure of the surfaces and the bulk alignment of the liquid crystal is developed. This enables device properties such as speed, contrast and viewing angle to be improved uniformly over the panel.
