Abstract
The present invention relates to an composition for spacer formation and a spacer element using the same, and more particularly to an composition for spacer formation comprising a) 10 to 70 parts by weight (dry weight) of a polymer emulsion; b) 0.1 to 50 parts by weight of a wetting agent; and c) 20 to 90 parts by weight of a solvent, and a spacer element using the same. The composition of the present invention has a significantly low viscosity and can be sprayed easily by inkjet, so that it is useful for spacer formation in liquid crystal displays.
