ABSTRACT:
A method for treating an aligning film for a liquid crystal display element wherein an aligning film consisting of an organic high molecular compound formed on a transparent substrate with a transarent electrode is subjected to a robbing treatment and thereafter said aligning film is irradiated with soft X-rays in a gas.
A method for preparing a liquid crystal display element comprising the steps of arranging a transparent electrode on a pair of transparent substrates, forming an aligning film consisting of an organic high molecular compound on the said transparent electrode, treating said aligning film by a rubbing treatment, assembling the substrates to face each other with a spacer disposed therebetween, and then applying and sealing to a substrate a liquid crystal material wherein the aligning film is subjected to a robbing treatment and thereafter said aligning film is irradiated with soft X-rays in gas.
