Ferroelectric liquid crystal with pitch 1-2 times layer thickness and graduation by bistable/monostable ratio |
摘要 |
A ferroelectric liquid crystal display element equipped with a ferroelectric liquid crystal layer exhibiting a bookshelf layer structure and having a helical pitch of about one or two times a thickness thereof. A ferroelectric liquid crystal display element equipped with a ferroelectric liquid crystal layer holding a mingling state of two areas: one is an area where a polarization direction after removing of a predetermined voltage over the threshold voltage for a spontaneous polarization remains as inverted; and the other is an area where the polarization direction is again inverted back to the original.
