COMPOSITION FOR FORMING TRANSPARENT ELECTRODE PROTECTIVE FILM OF LIQUID CRYSTAL DISPLAY ELEMENT AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PURPOSE:To obtain the coating film which cures at a low temp., has excellent wettability and is free from repellent phenomena by forming the electrode protective film of a compsn. composed of specific terminal hydroxy ladder polysiloxane, specific org. metal compd. and solvent. CONSTITUTION:The transparent electrode protective film is formed by using the compsn. prepd. by dissolving the terminal hydroxy ladder polysiloxane which is expressed by general formula I (where R1 and R2 are hydrogen or monovalent hydrocarbon group; n is a positive integer) and in which =55% of R1 and/or R2 of the general formula I consists of a phenyl group and the number average mol. wt. is 2,000 to 500,000 and the org. metal compd. expressed by general formula II (where M is a metal element; R' is hydrogen or monovalent hydrocarbon group; m is a positive integer) into the solvent. As a result, the protective film which is cured by a low-temp. heat treatment is formed and the long-life liquid crystal element is obtd. without increasing the sheet resistance value of the electrodes.
