Plastic liquid crystal display element

Abstract

Abstract PURPOSE:To obtain an excellent element having the films cured at the temp. at which no damage is given to plastic base plates and having good solvent resistance, water resistance and transparency by using an alkyd melamine polymer for the films for orienting a liquid crystal of a liquid crystal display element using the plastic base plates. CONSTITUTION:Patterned transparent electrodes 12, 17 are respectively formed to plastic base plates 11, 16 consisting of a polyester film or the like and orienting films 13, 18 are formed to cover the electrodes 12, 17. A compsn. contg. an alkyl melamine polymer which can be cured at a relatively low temp. to obviate generation of thermal deformation, etc. to the plates 11, 16 and is made hydrophobic by alkylating and esterifying the silanol group of the fine particles of silica colloid is coated as a material for the film 13, 18 on the above-mentioned base plates and is cured, then the films 13, 18 are subjected to an orienting treatment. The liquid crystal display element having the oriented films which have excellent orientation for the liquid crystal 15 and has good solvent resistance, heat resistance and transparency and having good durability is thus obtd.
