Conventionally, in liquid crystal filling containers, such as cells of liquid crystal display devices, as shown in FIG. 2, a flat substrate (1) (1'), display electrodes (2) (2') on top, and an alignment film (3) (3')
The pair of substrates were fixed together with an adhesive (5) to form a container. In this case, the pair of substrates has a flat substrate (1)-alignment film (
3) - Adhesive (5) - Alignment film (3') - Flat substrate (1'
). In other words, the factors that determine the adhesive strength of this pair of substrates are: - The adhesion between the substrate (1) (1') and the alignment film (3) (3') - The alignment film (3) (3') and the adhesive (5) is the adhesive force. These conventional general containers have a certain track record and have not caused any major problems in use.

のみ強誘電体層を除去する工程が必要である。However, there is a liquid crystal filling container that uses a ferroelectric layer on the alignment film or in place of the alignment film. Examples of such ferroelectric materials include copolymers of vinylidene fluoride (hereinafter referred to as VDF) and ethylene trifluoride (hereinafter referred to as TrFE) or ethylene tetrafluoride (hereinafter referred to as TeFE), polyvinylidene fluoride, etc. is known, and is a so-called fluorine-containing polymer compound. In the case of liquid crystal containers in which these fluorine-containing polymer compounds are formed on the top surface of the alignment film or in place of the alignment film, the adhesion to the underlying material is weak, and the adhesive strength between the top surface of the ferroelectric layer and the adhesive is weak. Therefore, it is necessary to remove the ferroelectric layer only at the bonded portion.

実施例に従い本発明を説明する。That is, when forming a liquid crystal filling container using such an organic ferroelectric material, it is necessary to use an adhesive containing a solvent that dissolves a polymer compound, or to use a solvent that dissolves a polymer compound. By adding it to an adhesive, a pair of substrates are bonded together, and essentially only the adhesive force between the substrates and the adhesive determines the adhesive strength. less than,
The present invention will be explained according to examples.

Random copolymer of FE (75χ:25χ) was methyl
The other substrate (1) was spin-coded with a 5χ solution dissolved in ethyl ketone (MEK), formed to a thickness of approximately 1000 mm, and the solvent was removed in a vacuum dryer to form a ferroelectric layer (4). ') was also subjected to the same treatment. Thereafter, in order to fix both substrates together, an outer peripheral seal portion was formed on one substrate (1) by screen printing using an epoxy adhesive. At this time, since the epoxy adhesive does not contain a solvent, the ME
K is added. After that, both bases were crimped to 80"
A heat treatment was performed at a temperature of C for about 30 minutes to harden the adhesive and form a liquid crystal filling container. At this time, the ferroelectric layer (
4) was dissolved or mixed with the solvent in the adhesive (5), and the substrate (1) (1') was in direct contact with and fixed to the adhesive (7) (7'). Adhesive strength is the tensile strength value of glass and epoxy resin (approximately 39Q kgcm-”)
The adhesive interface was essentially only the adhesive and the glass substrate.

It is not particularly limited. Furthermore, when using other types of adhesives, it is also possible to add a solvent or use a material containing a solvent.
また、本発明の対象とする容器は、実施例第1図のみに
限定されるものではなく、幅広い応用が期待できる。Further, the container to which the present invention is applied is not limited to the embodiment shown in FIG. 1, and can be expected to have a wide range of applications.
