Title:
FERROELECTRIC LIQUID CRYSTAL ELEMENT
Document Type and Number:
Japanese Patent JPH01120536
Kind Code:
A
Abstract:
PURPOSE:To increase an apparent tilt angle and the quantity of transmitted light and to improve optical quality in an extinction position by providing an oriented film formed with a diagonally vapor deposited film on a thin org. film subjected to a rubbing treatment, etc., on one electrode substrate. CONSTITUTION:ITO electrodes 2 are patterned and formed on the glass substrate 1 and an SiO2 film 3 is formed on the electrodes 2. After polyimide is coated as a soln. on the film 3, the coating is calcined to form the thin org. film 4 and the film 4 is subjected to the rubbing treatment by using the acetate cloth. The diagonally deposited film 5 of SiO is then formed on the film 4 in a perpendicular direction. Two sheet of the resultant substrates are disposed to face each other in such a manner that the incident directions of light are opposite to each other and the particles of SiO2 are uniformly sprayed as a sealing member 6 in the cell. The upper and lower substrates are stuck to each other and a ferroelectric liquid crystal 7 is injected into the cell. After the cell is heated up to the isotropic phase of said liquid crystal, the cell is subjected to adequate slow cooling at the time of a phase transition, by which the orientation uniform over the entire part is obtd.
