Title:
PRODUCTION OF LIQUID CRYSTAL PANEL
Document Type and Number:
Japanese Patent JPH04199128
Kind Code:
A
Abstract:
PURPOSE:To obviate the scattering of spacers with static electricity and to suppress the scattering of the spacers by the reaction of a mask when the pressing of a squeegee is released by using the gap materials formed by incorporating the spacers into a high-polymer material. CONSTITUTION:The gap materials 3a are formed by incorporating the spacers 3 consisting of, for example, fine silica powder into polyimide 2. The mask 4 is imposed on a substrate 5 and is adjusted in position in such a manner that light shielding parts 7 and apertures 4a mate each other. While the mask is pressed by the squeegee 1, the gap materials 3a on the mask 4 are moved toward an arrow A. The substrate 5 selectively stuck with the gap materials 3 only in the light shielding parts 7a of the substrate 5 is obtd. if the mask 4 is removed from the substrate 5 thereafter. The substrate 5 is then heated immediately to evaporate the solvent of the polyimide 2 by which the polyimide is tentatively cured. Further, the substrates 5, 5' are stuck at a specified spacing and the polyimide is finally cured to maintain the exact inter-substrate spacing.
