Abstract
A liquid crystal display cell, and a fabricating method thereof, that incorporates a light-cured monomer in a ferroelectric liquid crystal. By injecting the light-cured monomer/ferroelectric liquid crystal between substrate while in a nematic phase or isotropic phase, by performing DC voltage treatments as the liquid crystal temperature decreases, and by performing a light irradiation treatment, a stable, aligned ferroelectric liquid crystal cell is produced. Such a ferroelectric liquid crystal cell can reduce flicker and can be realigned after a physical shock.
Claims17
A ferroelectric liquid crystal display, comprising:
- an upper substrate having a first alignment film;
- a lower substrate having a second alignment film, wherein said lower substrate is attached to said upper substrate such that said first alignment film and said second alignment film face;
- and
- a ferroelectric liquid crystal interposed between said upper substrate and said lower substrate, wherein said ferroelectric liquid crystal includes a polymer network.
A method of fabricating a ferroelectric liquid crystal display, comprising:
- providing an upper substrate and a lower substrate;
- forming alignment films on the upper and lower substrates;
- joining the upper substrate with the lower substrate;
- interposing a ferroelectric liquid crystal having a light-curing monomer between the joined upper and lower substrates;
- applying an initial DC voltage across the liquid crystal;
- subsequently applying a second DC voltage across the liquid crystal, wherein said second DC voltage has a polarity opposite that of the initial DC voltage;
- and
- irradiating light onto the ferroelectric liquid crystal such that the light-curing monomer forms a polymer network.
