Spacer for liquid crystal element

Abstract

Abstract PURPOSE: To obtain spacers having a uniform particle size and to improve the sharpness of a display image by using carbon fibers which have a substantially round fiber sectional shape and are cut short in a longitudinal direction. CONSTITUTION: The spacers are formed by using the carbon fibers which consist of a carbon system, have the substantially direction. Since the carbon fibers have the uniform fiber diameter, the spacing is precisely obtainable and further, the circumference of two sheets of substrates are sealed by, for example, an epoxy sealing material at the time of assembling a liquid crystal cell and the above-mentioned fibers are not thermally deformed at the time of heating and pressurizing for the purpose of the sealing. Since the carbon fibers have the black color intrinsic to carbon and are not dyed or colored with a pigment, the fibers have the stability to obviate the elution of colors in a liquid crystal or the like. The carbon fibers do not flaw the ITO films or oriented films on the substrates at the time of maintaining the cell gap at a specified spacing by pressurizing two sheets of the substrates to some extent at the time of assembling the cell. The spacers having a good contrast ratio, good appearance and uniform particle size are thereby obtd. COPYRIGHT: (C)1989,JPO&Japio
