The liquid crystal is fixedly held in the gap, and the peripheral portion is sealed with a sealing material. The polarizing plate is arranged so as to sandwich the liquid crystal display element and imparts electro-optical characteristics to the liquid crystal display element.

る。On the other hand, plastic film liquid crystal display elements
A plastic film is used as the substrate instead of a glass substrate. When applied to liquid crystal display elements, plastic films are inferior to glass in terms of moisture resistance, heat resistance, optical rotation, liquid crystal resistance, solvent resistance, and scratch resistance, as well as being inferior to other materials. Because of poor adhesion and adhesion, the constituent materials of the liquid crystal display element are often different from those of the above-mentioned ordinary glass liquid crystal display element. However, the structure of a plastic film liquid crystal display element is basically the same as that of a glass liquid crystal display element. However, in plastic film liquid crystal display elements, it is common to provide a base film. This is a film formed between a plastic film substrate and a transparent conductive film, which improves the scratch resistance, solvent resistance, liquid crystal resistance, and moisture resistance of the plastic film. This improves the adhesion with the transparent conductive film (electrode pattern).

とができなかった。As a general requirement for a base film having the above-mentioned purpose, in particular, it is required to be a hard film in order to improve the scratch resistance of the plastic film and the adhesion of the transparent conductive film. As a general hard film, a silicone film is often used, which is formed by applying a silicone-based hard coating agent. , the adhesion to the substrate is weak, and adhesion is usually improved by using a substrate surface treatment agent called a primer to roughen the surface of the substrate or create a coupling effect. be. However, even if the adhesion is improved using a primer, the adhesion is weak to many plastic films such as epoxy, polyethylene terephthalate, and polyether sulfone, and such plastics that have formed a silicone film have poor adhesion. If the film was left in a high-temperature, high-humidity atmosphere, the silicone film would peel off, making it unsuitable for practical use as a liquid crystal display element substrate.

た。In order to ensure adhesion that can withstand practical use as a base film for plastic film liquid crystal display elements and hardness that is suitable for forming transparent conductive films, we developed two plastic films that have the respective characteristics.
We decided to mix the two resins to compensate for each other's shortcomings. That is, a polymer blend obtained by mixing a melamine resin and a co-condensate consisting of an alkyl alkoxy silane, an aminoalkoxy silane, and an epoxy-modified alkoxy silane is used as a base film for a plastic film liquid crystal display element. This improved the adhesion to the plastic film substrate, and also improved the scratch resistance, solvent resistance, liquid crystal resistance, and moisture resistance of the plastic film. Furthermore, since it was a hard film, it was possible to easily form a transparent conductive film on the base film and improve its adhesion.

しい問題があった。However, when a substrate on which a transparent conductive film is formed is left in a high-temperature, high-humidity atmosphere, the base film may whiten or crack. In addition, when a plastic film liquid crystal display element with this base film is left in a high temperature and high humidity atmosphere, whitening and
Cracks were seen. As a result, even if the lighting was good initially, after being left in a high temperature and high humidity atmosphere, there were significant problems as a liquid crystal display element, such as part of the transparent conductive film being disconnected.

In a film liquid crystal display element, the non-volatile solid content of the co-condensate consisting of an alkyl alkoxysilane, an aminoalkoxy silane, and an epoxy-modified alkoxy silane is reduced to one-half or less of the non-volatile solid content of the melamine resin. . As a result, in addition to improving the adhesion with conventional plastic film substrates and the scratch resistance, solvent resistance, liquid crystal resistance, and moisture resistance of the plastic film itself, it also has good adhesion with transparent conductive films and can withstand high temperatures and high temperatures. A plastic film liquid crystal display element was obtained that prevented whitening and disconnection of the transparent conductive film in a humid atmosphere.
