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.

Claims (10)

1. A ferroelectric liquid crystal display, comprising:

a 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 each other; and

a ferroelectric liquid crystal between said upper substrate and said lower substrate, wherein said ferroelectric liquid crystal includes a polymer network and is positioned at a center of a virtual cone formed by an initial alignment.

2. The ferroelectric liquid crystal display according to claim 1 , wherein said first alignment film and said second alignment film have parallel alignment directions.

3. The ferroelectric liquid crystal display according to claim 1 , wherein said ferroelectric liquid crystal is aligned in parallel with an alignment direction of said first alignment film.

4. The ferroelectric liquid crystal display according to claim 1 , wherein said upper substrate includes a color filter layer.

5. The ferroelectric liquid crystal display according to claim 4 , wherein said upper substrate includes a common electrode.

6. The ferroelectric liquid crystal display according to claim 1 , wherein said lower substrate includes a pixel electrode.

7. The ferroelectric liquid crystal display according to claim 1 , wherein said polymer network is formed from a light-curing monomer.
