Abstract
Disclosed is a liquid coating composition for forming a liquid crystal display element insulating film, which comprises a solution to be obtained by hydrolysis of Si(OR).sub.4 in the presence of an alkaline catalyst a hydrolyzed product of R.sup.1.sub.n Si(OR.sup.2).sub.4-n and/or Ti(OR.sup.3).sub.4, an aluminium salt and a deposition inhibitor, all having been uniformly mixed in an organic solvent. R, R.sup.2 and R.sup.3 each are a C.sub.1 to C.sub.5 alkyl group, R.sup.1 is an alkyl, alkenyl or aryl group, and n is 0 to 2. Though containing a trialkoxysilane having a high repelling property, the liquid coating composition may form an insulating film having high mechanical strength on a substrate and the coatability of a polyimide solution over the film is good. The adhesiveness of the oriented polyimide film to the insulating film is good. The insulating film has a high insulation property and has no bad influence on the display performance of liquid crystal display elements.
