Title:
PRODUCTION OF FERROELECTRIC LIQUID CRYSTAL ELEMENT
Document Type and Number:
Japanese Patent JPH06194615
Kind Code:
A
Abstract:

PURPOSE: To provide the process for production of the ferroelectric liquid crystal element which can prevent the degradation in display grade by arranging spaces for maintaining the specified spacing between substrates in parts deviating from picture element regions and can prevent the adverse influence of a sealing material on the ferroelectric liquid crystal by averting the contact of the liquid crystal to be encapsulated into the spacing and the sealing material of an uncured state.

CONSTITUTION: This method for production of the ferroelectric liquid crystal element consists in encapsulating the ferroelectric liquid crystal LC between a pair of the substrates 1 and 2 formed with transparent electrodes 3, 4. The columnar spaces 9a to be arranged in the parts averting the picture element regions A of the substrate 2 and the frame-shaped spacers 9b to be arranged in the parts along the peripheral edges of the substrate 2 are simultaneously formed by a photolithographic method on this substrate. In addition, the frame-shaped sealing material 10 is formed on the substrate 1 and the ferroelectric liquid crystal is dropped onto the substrate 1. The two substrates 1, 2 are then superposed and pressurized on each other in such a manner that the sealing material 10 is arranged on the outer periphery of the frame-shaped spacer 9b. The sealing material 10 is cured in this state and the two substrates 1, 2 are adhered via this sealing material 10.
