Title:
LIQUID CRYSTAL DEVICE
Document Type and Number:
Japanese Patent JPH04293016
Kind Code:
A
Abstract:
PURPOSE:To prevent one-sided distribution of spacers due to static electricity caused during manufacture by specifying an amount of spacers to be added and heat treating orienting films containing the spacers to fix them. CONSTITUTION:The polymer spacers 16a-16e of 6mum diameter are added into the orienting film material of polyimide are printed by flexopaphic press on ITO transparent electrode layers 12a, 12b formed on soda glasses 11a, 11b. The thickness of each of the orienting films 13a, 13b is 50nm, and an amount of spacers 16a-16e to be added is controlled to 100permm<2> of the printed orienting films 13a, 13b, and the soda glass substrates 11a, 11b are heat treated at 200 deg.C for 2 hours to harden the orienting films and to fix the spacers 16a-16e to the orienting films 13a, 13b, thus preventing the spacers from becoming one-sidedly distributed by static electricity occurring during the manufacture. The orienting films 13a, 13b are subjected to orienting treatment by rubbing them with rubbing cloths.
