The memory capability of the surface stabilized ferroelectric liquid crystal display in conjunction with the thickness of molecular alignment layer has been investigated. We clarified the thickness effect on the each part of polarization switching behavior. The thickness effect is interpreted by the space charge transportation in terms of polarization switchings of the ferroelectric liquid crystals. The improved memory capability due to the layer thickness research enables us to fabricate a high contrast ratio ferroelectric liquid crystal display with the XGA pixel.
